Don’t say yuck! Math is fun! A puzzle! A game!
Anyway, when I posted these blocks last week, I was asked how I figured out how much of the background yellow I needed for this quilt. I decided to try to explain that in a post.
First of all, my “blocks” will finish at 3 by 9 inches. There is a 3 inch square and a 3 by 6 inch print rectangle (finished sizes) for each.
I wanted my quilt to be approximately 60 by 72 inches. I find that to be a good nap quilt size. My blocks are 9 inches wide. So 60 divided by 9 is 6.667. I round up to 7 blocks wide which is 63 inches. A little big, but close enough.
Now I want my quilt to be 72 inches long and my blocks are 3 inches long. 72 divided by 3 is a perfect 24.
Now I know my block layout will be 7 by 24. Each “block” has one print rectangle and one yellow background square, so I need 7 times 24 or 168 of each.
Still with me?
Good. Now I’m going to start discussing in cut sizes. I can get 12 3 1/2 inch squares from one 3 1/2 inch strip of fabric cut selvedge to selvedge.
168 divided by 12 is 14, so I know I need 14 strips that I will subcut into 3 1/2 inch squares.
14 times 3 1/2 inch wide strips is 49 inches, which translates to 1.36 yards. I’d buy 1 1/2 yards to be safe.
These directions are for determining yardage using a rotary cutter and ruler. I would calculate a bit differently if I were using my die cutter, but that’s info for another post.
I’m a bit of a math geek and I can do these calculations mostly in my head. I realize not everyone can. It’s a puzzle to me and I enjoy it. I’m weird that way!
I hope this helps. It’s easier to do than to explain. I sure hope this makes sense. Have a great day!
