Never used a glue gun for this.... I dont think that it would work very well since it doesn't blow the heat out but if you can make it work, let us all know!
Hmm... never thought about coating the pliers in pam or anything, I dont know how it would turn out.
What I do is roll up the plastic, keep it rolled by using the pliers, then heat it. Sometimes I heat the whole thing till there is no hole at all, let it cool for a bit, then heat it back up long enough to stick a pin through the middle to get a nice small hole.
I just used scissors, but if you are having problems.. try using a box knife/razor.
They dont take long at all to make... just depends on how youwant them to melt. And if you use longer pieces of plastic they are not oonly bigger but take longer to melt but stay together much much better.. hardly any deformities.
hmm... I saw some heat/embossing guns at Hobby Lobby last week for under $20. And yes... I have used thefake credit cards and they work out well and you get some nice looking beads... specially the see-through AMEX ones heh.
Yes... some do get deformed and whatnot, but if you close up a hole just wait for it to cool, reheat, and poke a hole with something metal. The more heat yoou use the more deformed they become so even if you want to makethem fast... you may want tomake them slowly, waving the gun at them instead of keeping the heat right on them.
