♥ Diagonal Backing Calculator
 

Thanks Crafty, where have you been?

Thanks Crafty, good to see your name pop up!!

Yeah I tried this with a square 76" quilt and it told me I need 19 yards! I don't think so!

Thank-you for this link I have always just done a rough guesstamet in my head.
quiltmom04 this works great for small quilts that are up to 60" wide where you waste so much fabric getting 2 widths to sew together.

Thanks Crafty, so good to "see" you. I miss your wondeful links.

Thanks, Crafty.

Crafty welcome back always good to see your name and your posts .. Hope all is good with you and your family.

Thanks craftybear......this type of "arithmetic" makes sense to me...I hated grade school arithmetic...bkkg had a debit-credit-balance & quilting has a challenge that keeps me sew happy

I guess that I didn't understand this , Why would I want a diagonal backing, When I figured it out for a 65x 85 quilt with 3" on each side it came up with 8.6 yard. Seems a lot to me.I can use 6 yards by just piecing two 2.5 yard lengths together vertically. I know that I am not great at math but I drew this out and I think that 6 yards should do it. Unless there is a reason to use a diagonal.
