I use (or reuse) the card stock that is in all the magazines as advertisements or mail-in cards. It is the same as cardstock and does not cost me anything. Of course, I pay for the magazine. Last year I did a flag with 1/2" hexs
and it took awhile to do. Very small stitches too. I completed most of the flag, 294 hexs, and then took the papers out before I appliqued it to the sky background fabric. I framed it, took it out of the frame to put in the quilt show because it could not be framed for the show, now I have to put it back in the frame. Oh, well.
