Use card stock & print in a printer. Works very well. I now have one almost a king size. It is so easy to do this. I purchased a package of 100 pre-cut just to make sure my hexies were straight. I posted my GFG on here last week if you would like to look at it.
The time spent cutting the card stock is done when I have to takle my Mothger to doc & in eve when I need down time. Very relaxing Enjoy whatever method you do, but do it by hand, much more satisfying. You don't have to rush to get this done. I am going to hand quilt mine also. Good Luck
