yes I agree (that means you're right Yvonne!LOL) you gotta hve the piece with the points on top so you can see that your needle crosses where the threads make the little X, it may not be the exact 1/4" you're striving for but sometimes you just have to fudge a bit to make it do what you want it to do, you'll get there, by the time you finish your blocks you'll be amazed at how much better you are. the last 1/2 of anything I do always looks better, that's why a lot of things I start at the bottom!
