I love Command Strips but had not thought about using the refill strip to mark 1/4 seam! I have a ton of the extra ones that came with the hooks. I didn't even think about using the Command Strips to hold my rulers on the wall! I did use them to mount a "shoe caddy with plastic pockets" on the back of the closet door.
Off to print some coupons! BTW, Dollar General does have some of the smaller sets.
