Enter, Pinterest. Yes! Really, again! lol! I happen to follow several quilters & one of them pinned this tool. I read the post & decided it was worth investigating. So, I googled it, and found a couple videos on how to use it. After watching the videos, and finding them for sale on Amazon for a decent price, I decided to give it a shot. I'm so glad I did! It is the best quilting tool I've ever purchased!!!
How this differs from any of my other tools, is that it attaches, more specifically, it sticks to the bottom of the actual presser foot!! Why I think this worked for me, is because you have the scant 1/4" measured from the actual needle to the outside line - not from the edge of a tool to the needle. Do you see the small hole? Well, that's where the needle goes. Just make sure the solid line down the middle lines up, and Bam! Perfect seams!
I'm tellin' ya, I think my needle is off-center! Once I put this on my presser foot & started sewing my half-square triangles, I could not believe the accuracy!! I actually had to square down the blocks for the first time ever! All of my points were perfect. All of them! I was so happy!! After years of struggling, I had finally found something to help me achieve that perfect seam! YAY!
If you read all the info about the Sew Easy Guide, you'll see that it's original purpose was for sewing half & quarter square triangles without marking. I do have to mention, that my half square triangles were far too big (10") for the tool. I still had to draw the diagonal line down the block. But! That was the only marking I had to do! I just lined up the solid line from the tool, with the solid line on my block & the tool helped me keep it all straight! It's so simple, it's genius.
If you're havin' issues with your seams, or just hate drawing all those ridiculous lines for your half & quarter square triangles, I highly recommend purchasing this. It comes in 2 sizes. I got both! Thanks, again, Pinterest!
