Are Your Card Sleeves Too Wide?
Categories: [ DIY ]
I bought a pack of 25/8 x 35/8 card sleeves to protect my Citadels character cards, but they are of course too wide (they are meant for Magic The Gathering cards). The guy at the shop suggested I could melt the side with a lighter, but he meant it as a joke (I hope). But what actually works (I just tried) is a soldering iron.
The sleeves are made of polypropylene, which melts at about 170 °C, but doesn't burn before 570 °C, so it's quite safe if you have an adjustable temperature soldering iron. I tried to tracing a line slowly on the sleeve along a piece of PCB board (because it's a heat insulator, I wouldn't have tried this with a plastic or aluminium ruler), and it made a nice seal. I suppose that cutting along the seam with a hobby knife would remove the excess plastic without destroying the sleeve.
Next step, mass production (that is, 9 sleeves for the basic characters, and 10 more for the extended characters).
