Using resin and foraged natural items we made fun jewelry! You can also make paper weights, fridge magnets, belt buckles, wall pieces, etc.

Step 1: Make Molds

I used the vacuum former to heat and form sheets of plastic (from Tap Plastics you can get sheets of Polypropeline) to make molds. I like working with nature so I used pieces of wood, bark and pine cones cut in half lengthwise. I had to cut the pinecones or else the plastic would wrap around them and I wouldn't be able to get them out. No undercuts. I also got one pre-formed mold sheet to accomodate many small resin pieces to be made.
When i use the resin spray it makes my resin appear super matte and foggy ? what am i doing wrong?? I tried adding a fresh layer of resin but its making it worse bc it drips or is uneven or if i use a brush ir sponge to add a thin layer it leaves streaks! Help mee!
I've heard that any resin left uncovered (like in the open top of a mold) will stay tacky and never fully cure. Is that true? How would you keep that from happening?
<p>I have had that problem. I was wondering if this is what the resin spray is used for?</p>
Love this! Do you know if resin works on any plastic mold?
No it does not. Sometimes it will become one with the plastic mold and not ever get out and sometimes it is just extra hard to demold. You can always use mold release but it tends to leave a weird surface finish as it bubbles between the plastics. I vacuum form either LDPE (low density poly ethiline) or regular PE. If you dont use a vacuum former, most tuppaware works well and it has some flexibility to make for an easy demolding. I've used bottoms of plastic bottles, sometimes they have fun shapes. It's difficult to demold but possible with some force. Best of luck to you!!!
<p>I've been working on a bottle cap table and I cover it with plastic sheeting to keep dust out of the resin. It doesn't seen to stick to that stuff. I don't know off hand what kind of material it is(maybe vinyl?) but I can say that I bought it from Home Depot in a roll. Maybe in the paint section? I originally bought it as drop cloth for painting. I'll see if I can find out what the material is and the next time I do a pour I'll test to be sure it doesn't stick. I got some resin on it at one point and after it had cured it seemed to just pop off when the plastic was moved.</p>
