yes, I do some basic card weaving.
Just the 4 forward, 4 backward things.
Beginner tips? Let me think.
*Dont start with more then 12 cards. That is easy enough to handle in the beginning. And less time to get it set up.
*dont use too small cards, it will drive you nuts.
*make sure you load your yarns through the cards the right way ( direction). Otherwise your pattern doesnt come out right.
*it looks best when the 2 outside cards on both sides are the same colour as the yarn you weave with.
*have something to remind you which direction you are going. I use sometimes a pair of scissors. Put it on the table next to you. When the point is facing away from me, I go A,B,C,D. Then turn it around. When the point is facing me, I do D,C,B,A.
Just in case you get disturbed halfway.
* use a rubber band to ty the card together when you want to put it away.

Hope this helped a bit.
Do you do backstrap or a rigid loom?
