Square in a square, mine is wonky
 

Please share your secrets to making a perfect square in a square? Is there a magic ruler like Deb Tucker's Wing Clipper? Can you make your triangles a little big and trim the block? I'm not a perfectionist, I try but I keep failing, :) but my Square in a Square is just way too wonky. Thanks everyone!

Paper piecing works every time.

Cutting the pieces so that all the grainlines go the same direction has been helpful for me.

Also sewing the triangles on opposite sides first, instead of attaching the pieces 'around the square'

I agree with bearisgray and remember when pressing to not move the iron around just press up and down as not to stretch the block's.

PS: I want the grain lines on the outside edge of the unit to be on the straight of grain.

I haven't used it but my friend uses the Square In A Square ruler from Jodi Barrows. She made a lovely Storm at Sea quilt for my daughter using it, and said that it was easy to use. She also said that there was quite a bit of waste but that the scrap pieces were large and would be useful if you are a scrap quilter (she is not). But as I said, I haven't used it personally....

I do not prewash my fabric and use the Accuquilt Go! to cut the triangles. The triangles are perfectly cut with corners nipped off, so they are very easy to align with my squares. Not prewashing ensures the fabric has some stability. If I prewash a fabric, I starch it fairly heavily before cutting to add back some stability. Starch, when heavy enough, prevents even bias edges from stretching.

yes deb tucker males one I have it luv it only makes up to 61/2 don`t know if there is a larger one

This woman speaks my language, it worked well. Thank you so much!
