hexes- i got the fiskers punch in 3/4" at michaels, i like to use heavy card stock or manilla folders. i'm doing three tog, one on top of two.
My travel sewing kit is a 6 x 12 inch pieced work and sewn around a 2 1/2" yo yo. i put cardboard 2 1/2" with a pc of batting in it and sew the yo yo around it. make two of these. sew the pieced pc of fabric ( i do strip piecing) long sides to the yo yo. about 1 inch unstitched. do this on both sides. i sew a narrow pc of ribbon to tie it up. On one side inside the rollup on the yo yo inside, i make a small incushion. i cn keep needles, pins 3-4 spools of thread and scissors i it, oh and seam ripper. these can carry alot of stuff. my quilt in under pictures probably 5-6 pgs in now titled lynnies hex quilt, posted by a friend. good luck with the surgery and with your hexes.
