Love ruler. Works great for piano key. Haven’t done cross hatch but plan to use ruler for this. Bought both sizes so I can do all kinds of stitching.

I agree with previous reviewer that suggested better instructions for ruler. I have watched Angela demonstrate it though. I am a new longarmer so I think this will be helpful as such.

I'm very excited to create a quilt that would benefit from this ruler. Unfortunately I've just had knee replacement surgery and can't stand long enough to do anything. I've actually had a few dreams about pairing this ruler with various p2p triangles or swags in my Quilt Path inventory.

At first I thought a simple straight edge would suffice to make crosshatching. I soon discovered that accuracy was difficult. Enter the Quilters Groove Proline 2. A game changer! The markings make it easy to line up in any direction. Love it!

Love this ruler. I bought both sizes and they are very useful.
