Haven't used it yet, but am obsessed about the scant 1/4" so I'm really looking forward to it.

I use this as an edge to keep my seam allowance straight.

Great service and product....just wish I knew I needed another product too (can’t remember what it’s called - some sort of other guide...only reason for 3 stars...it’s not available currently so I did ask to be advised when it’s available!

I’m sure it would work. However there wasn’t enough how to use info in the package. After review of on line info, also not totally clear, I pulled off what I believed was a cover to find I tore off the sticky part, rendering my tool useless.

Great to get accurate seams - takes the guess out of where your are sewing your seam
