On a lot of EQ's print outs, I have found if I use a scant 1/4" I don't lose my points. Or I use my ruler to cut a bigger seam allowance and then use a true 1/4" seam.
When I do these curves, I pull the paper off and then sew the pieces together. The paper seems to get in my way and it can shift on the curves. I put the solid piece on the bottom and the pieced on top, as the unpieced always seems to want to stretch more. But I know others who do the opposite LOL
I also only pin at the beginning, end and middle. The more I pin, the worse it turns out it seems. The last curved pieceing I did, it was suggested to just pin the beginning and it was the best I had ever done... but that could have been a fluke, too LMBO I had to try different feet and methods on scraps to finally find what worked best for me :D:D:D
