I have one and then realized that all my templates and rulers and the 1/4 allowance.

I don't use them...I just use my quilting foot that has the edge guide.

I love gadgets and if I think it will help me then I am all for. I will be check into this for myself. Thank you for a great question. Now I will finish reading everyone's reply, and see if for me.

send me one of those right away - I'll use it ... hehe

Have both of them. Used them some, but hate them.

I have them and use them all the time for drawing the diagonal line for HSTs. I use that line as the guide for my quarter-inch foot and then cut on the line. Of course, I could use any of my multitude of rulers to do the same thing, but the fact that these are small and thin somehow makes it seem like they are easier to use. I love them.

I love mine they're so easy to use and they're great even bought a set for my sister in law, who started me quilting

I like them.

I have 2 a short one and a long one. Use them all the time.

Bought one quite a while ago but have not had opportunity to use it yet. Think I will love it.
