I got resin on my skin, how do I get it off?

First, wipe off as much as you can using dry paper towels, then wash well with dish-soap until you're no longer sticky. Baby oil works well, as do orange-based cleaners. Little Windows resin is not a toxic product, but it can cause irritation if you have sensitive skin. Get medical attention if you see swelling. If you get it in your eyes, flush with water for 15 minutes and get medical attention. Keep eye lids apart. If someone drinks it by mistake, give them large quantities of water and get medical attention.

What Can I Do To Minimize Bubbles?

When working with resin, bubbles are a fact of life, and probably the biggest variable, but there are many ways to avoid/reduce/eliminate them. Your Little Windows how-to guide, and our How-To Videos have tips and tricks at every step. Beyond printing on Little Windows papers, which are waterproof, here are the basics:

1)   If your bottles have been moved around or shaken, LET THEM SIT STILL for about 30 minutes to settle.

2)   If your Little Windows Part A (Resin) has gotten cold, it may have thickened up. The thicker your resin, the harder it will be for bubbles to rise, so you'll want to WARM IT UP.  You can measure out your batch into the mixing cup, then pop the cup in a microwave for 5-7 seconds, until the outside of the cup is just warm to the touch.  DO NOT TRY THIS WITH ANY OTHER RESINS OR CHEMICALS, AS THEY MAY GIVE OFF DANGEROUS FUMES.  Another option would be to tighten the lid on your Part A, put it in a zip-top bag, and soak it in hot water for 15-20 minutes.  Allow it to cool down to about room temp before mixing in your Part B.  Do not heat Part B, do not heat after you've combined A and B.

3)   Try to avoid adding bubbles while you stir. STIR SLOWLY AND GENTLY, and be sure to scrape the side and bottom of the mixing cup. Stir for the recommended amount of time. 

4)   LET YOUR MIX REST for 5-6 minutes before you pour, to allow blending to complete, and let bubbles to rise and pop. If there are any bubbles clinging to the top or sides of your mixing cup, scoop them out before you pour.

5)   POUR RESIN SLOWLY into your mold, and slide in your photos into the resin, face-up. Wait a few seconds to let the photo settle down into the resin, then use your mixing wand to slowly push the photo to the bottom. Cover up your mold and wait the recommended amount of time so the bubbles have a chance to rise up and pop on their own.

6)   After 10 minutes, if you see any stubborn bubbles clinging to your photos, use your mixing wand to gently scooch them off and up into the mixture toward an edge, so they have a chance to rise up and pop on their own.  Give them a few minutes then scoop any remaining bubbles up and out of your mold.

7)    Another way to avoid bubbling is to pour in thinner layers, which also allows you to collage and create 3-D effects!

8)   Watch out for pigment inks in your printer, they may cause tiny bubbles to form and cling to the surface of the photo.

How Do I Even Out My Top Edges?

When you're working with molds, the resin creeps up the sides a bit, so your top edges will be a bit higher than the middle. This enhances the beautiful reflections around the sides of the piece - the higher the sides, the more dramatic the reflections you'll see.

Sometimes you might want them lower, or smoother.  There are two ways to do this:

You can simply trim around the edges and corners using small, sharp scissors, or you can sand them down using fine-grit (600+) wet/dry sandpaper you'll find at any hardware store. Before you begin sanding, you might want to use your scissors to trim the edges and corners down. Then, wet the sandpaper, place your piece face-down on the paper, and rub it around in a circle until you achieve the look you like. Just be careful to stop before you begin to scratch the face of your piece. Then dry off your piece using a paper towel or tissue.

Another fun technique to make your pieces smooth and rounded, is Doming-Up (see How-To Video in our Project Center), which is adding a domed layer to your cast pieces. You can embed anything into this second layer, to create beautiful dimensional effects!

Printer Settings

Sometimes it's tricky to find the right settings to print the 4x6" files you've created using our Little Windows Photo Croppers.  Our amazing customer Barbara sent us this guide to help you find what you need:

What if I don't have a color printer?

Well, you have a few options:

- Crop your photos online, then email your file to us for pro printing. It's just $2.50 per 4 x 6" printed sheet, and will be shipped out to you within 2 days after we receive your file/s.

- Have a friend with a good printer? Email your files to them to print, or go visit the and crop online at their house, printing once you're done.  You can use the Little Windows Photo Cropper wherever you have internet access, and the use of either Firefox or Internet Explorer as your browser.

- Take your files to a printing place, but make sure they either scale them to fit a "Borderless 4x6" sheet, or that they print your files at 34%, onto Little Windows Special Photo Paper. Each Medium Square cropped photo (for example) should measure 1 inch.

I see bubbles even after I scooped

Sometimes you'll scoop out all bubbles, then come back a while later and see a bunch more in one spot on your piece, usually on one edge or corner.  That means there was a larger air bubble trapped behind your paper, and as the resin starts to set up, that bubble makes its way up and around the edge of the paper in a stream of smaller bubbles, almost like a fountain. 

To prevent this from happening, carefully lift up your mold and check below your paper to see if there is a bubble hiding there (keep your mold level so the resin doesn't flow out).  If you see a bubble, you can either press the paper down against the bottom, forcing the bubble up all at once, or you can lift up the paper, allowing bubble-free resin to flow beneath it, then gently push the paper back down.  Allow bubbles to rise and pop.

My Print Quality Is Poor

If your print quality isn't as good as you'd like, check that the images you're using are high-resolution (300dpi), then be sure you've selected the highest quality print setting your printer will allow. Also, be sure you've told the printer you're using high-quality glossy photo paper. If you're still not happy with the results you may want to try our pro-printing service, available in our shop. You just email your cropped LittleWindows.png file to us, and we will print them for you and mail them back within 48 hours. Depending on where you live, you should receive your printed photos within 1 week.  Faster shipping is available.

DRILLING RESIN: How Do I Make Holes In My Pieces?

Our Little Windows Starter Kit includes a Spring Drill which is the perfect tool for making small holes in your resin (or wood). The kit comes with 1 drill bit which is 1.2mm.  The Spring Drill is also available individually, and includes 3 drill bits (1mm, 1.2mm, 1.5mm).  

This drill is easy to use and will not cause hand fatigue.  It works by moving the handle up and down, which turns the drill bit.



If you have any trouble fitting the drill bits into the collets, watch this video:


The original Little Windows Kit comes with a mini-hand drill which works by pushing down on the end and twisting it through your resin. 


If you plan on making more than a few, you can also use a power drill like the Creative Power Drill, or a Dremel tool with a #60 or 61 drill bit.

How do I shrink my pictures to fit?

The easiest way is to use our cropping software developed specifically for making Little Windows!  It is a web application, so you will access it here on our website. You will be working online without downloading any software to your computer, the only thing you'll save to your desktop is your finished, re-sized sheet of cropped images, which will be saved to your desktop so you can print it at home. The Medium 1" Square Cropper Shape is available for you to try for FREE. 

If you like how it works, we offer Croppers for all Small and Medium Mold shapes. Below are the dimensions for all croppers we offer.

You can also use Photoshop or another photo editing program if you prefer, and then use the Little Windows Photo Cropping Templates that come in the Starter Kit and Mold Sets (also available for $2 in our shop).

If you're not comfortable cropping online, or using Photoshop, click here for a How-To guide for resizing your pictures using Microsoft Word or GoogleDocs.  This will also work if you need to resize your images to fit our Large Sized Molds or Hearts Molds.  You'll then use the templates that come with your molds to trace around and cut out your shapes.

My Cropped Pics Aren't The Right Size

If your pictures are not printing out at the right size, check your Print Page Setup, to be sure you've selected 4 x 6" Borderless printing. If your printer does not allow for this option, then find the "scale" variable, and set the document to print at 34%.

Paper Punches

We offer custom paper punches to fit some of our molds, which can also be used for Doming, or for any craft/scrapbooking project, with or without resin:

Our 1" Rounded Square Punch fits our Medium Square mold shape and saves lots of time.  It's the only one on the market with rounded corners, so you can use it for lots of other things as well, including Photo Cube gifts.

We also have heart-shaped punches in 1", 1-1/2", 2" and 2-1/2" sizes (side to side), that fit our Heart Shaped Molds.  Again, these are excellent for paper crafting as well.

We launched these punches recently, and will add more to fit our other mold shapes as we grow.  For any of our Circle Mold Shapes, you can find punches at your local craft store or online.

Small Circles Mold - 5/8" punch

Medium Circles Mold - 1" punch

Large Circles Mold - 2" punch
