Hi DM, Here's a how to video that may help: https://www.youtube.com/watch?v=8xdsVrIpdpo
Hello DM, here's what one Hometalk poster did. She used a waterproof shower curtain for the base so moisture from grass won't affect the picnic!
I saw this post but can't find it again. Just cut & sew denim squares into basic quilt then add either water proof shower curtain,vinyl cloth backed table cloth or black-out rubber backed curtains to other side,putting cloth side of these a up against blue jeans and water proof side out.This provides dry sitting area.If you cannot sew here is no-sew idea using other materials https://thesurvivalmom.com/diy-no-sew-waterproof-picnic-blanket/
here's one idea:
I want to make some toilet and bathroom floor mats from old blankets.
How to make denim picnic blanket?(Saw it, then disappeared and couldn't find it again!) Thank you!
