Calico Cat asked why 10½ blocks made the quilt more fat quarter friendly... I tried to answer just her, but it was a no-reply addy, then I thought maybe others would be interested in my math. So here goes!
Most fat quarters are 22x18 ish...right?
Sometimes you lose a bit if you prewash them like I do. I fold the FQ in half (making it doubled 11x18, following my math?)and by the time I trim the frayed edges off it's a doubled 10½x18.
I could only get ONE 12 inch square from a FQ, but can get two 10½ inch squares. That leaves me with a nice size hunk (18 take away 10½, and take away the other frayed edge = 7) so my hunk leftover is about 21x7.
21x7 is a good size for a leftover bit... cut that in half longways and you have 21x3½ strips which are a great size for scrappy borders or bricks.
OR Cut it in thirds and you have three 7 inch squares... Throw those together with some background fabric and make half square or quarter square triangle bits...OR cut those 7 inch squares in quarters and you have twelve 3½ squares. If you have several coordinating FQ's you'll have lots of matching squares or strips to use in your border.
See how that can make a fat quarter friendly and fun to play with and easy to use almost all of it?
