When gluing cards together, is there such a thing as a "Jig" to align the cards? If so, where might I find it?

You can find one in the corner of a box. I don't know if you were looking for something more sophisticated but I imagine that would work fine.

Stupid me, why didn't I think of that? Thanks a million for your suggestion Robertology.

A couple 1x3's or similar stapled to a piece of plywood would be sturdier I suppose - if you're doing a lot. A shoe box would flex quite a bit but I'm not sure that would matter much down at the bottom.

Or get a small picture frame at a second hand store. Some tape on the inside to keep the cards from slipping through should give you something solid. Or just place a piece of cardboard in there first to cover the gap. I've never tried any of this but it sounds like a good idea.

Wow...Thank you for all of the suggestions!

Here ia a Youtube video from Marty Grams "The Art Of Card Splitting". It Shows his alignment board about halfway through.
