You can make beautiful, everlasting roses with Little Windows Resin Color Film, a Silicone Doming Tray and some wire. First, cut petals out and dome them with Brilliant Resin. The shapes on the left below have resin applied.
This technique mimics the now-outlawed wire-dip from long ago (toxicity=bad).
Create wire shapes as outlines for petals and leaves. Dip into resin and place onto Resin Color Film. The resin will adhere the wire to the Resin Color Film.
Allow to cure, then cut around each shape close to the wire, place them on your Doming Tray, and dome each shape on the wire side (sorry, I forgot to take a photo of this step, but I'm sure you can imagine it :) After 12 hours bend the petals and leaves into shapes you like. The wire should hold them in place, but you can use Amazing Tape if needed. Then arrange them however you'd like, and twist the wires together. Then wrap the stem with green wire for a more finished look. I'm not a tidy wire wrapper, so I'm embracing the lumpiness!
