Looking for that perfect gift is alway hard to find. I have a great idea for you. Find your favorite photo and cap (metal bottle or jar lid) and turn it into a necklace or Christmas ornament. I could just imagine a Christmas tree with all my favorite moments of year that I captured with my camera hanging as epoxy Christmas ornaments.
Printed a picture small and cut it to size.
Colleague once told me once "Always good things are mess" Epoxy can be very mess so wear gloves and cover your area. It is also very important that you measure equal part A (Resin) and B (Harder). Make sure you buy the pour epoxy. I got my at Menards &/or National Arts and Craft.
Let dry a day. Then super glue on a clasp, I got mine at Dephi. Find a chain you like and put it on!
