Hi... I love batiks too. First quilt I ever made was last year and it was a queen size for my granddaughter. Don't remember the name of the pattern, but it used the plastic templates with lots of curves... and 2 different sizes of templates. She loved it, fortunately!
Thought I'd never get it finished tho.
Could you post some pics of the bags you make? I still have lots of fabric left over and would love to use them for something like that for gifts.
