My absolute favorite tools are my Dritz Ultra-Fine Glass Head pins. I know they are kind of bendy. But, I love that they don't leave marks in my fabric. I'm willing to deal with that little point. And, my 8" Bias Square by That Patchwork Place. I know that you shouldn't have to square up your blocks. But, I always have to. This baby keeps my half square triangles spot on! And the last thing is my Quick & Easy Block Tool by C T Publishing. (It's 102 Rotary-Cut Quilt Blocks in 5 Sizes.) I wish I had found this a long time ago. It is Awesome!
I look forward to seeing what other people love.
