This is the way I've always done it (for the few quilts I've made).
Usually, I make one of those continuous strips --- Help me! what is it called? --- but would LOVE someone to tell me what the formula is when you don't need a full yard sewn and cut on the diagonal.
I always end up with strips I don't need and wonder if I'll ever find a use for later.
I saw it once somewhere and should have taken notes!
(Length x width) x 2 + ??? = ???
I like this way because the double fabric and the bias makes it easy to bind around uneven seams ( ! ) and makes it tight and wears well over time.
Thanks!
