I know they can be rotary cut, but for the life of me I can't figure out how to calculate how many strips I'd need to cut.
Hoping someone will help me out. Soooooo....
If a quilt patterns says to cut 28 2x12-inch strips and my material is 44 inches wide...how many strips do I cut?
What is the formula for calculating that.
Sorry to be such a dummy.
I have a Master's degree but it wasn't in math. LOL
Stuck here.
TIA,

Get yourself a cup of coffee and a caluclator and look at this again. It's a whole lot easier than you are trying to make it.
Use your calculator. Your fabric is about 42" of usable fabric (doesn't count the selvages) Divide 42 by the length of your NEEDED piece. So for the 12 inch pieces you'd get 3.5 strips that are 12 inches long. Use 3 and the half one which would be 6" lay aside for something else.
IN 25 words or less, anything to the right of the decimal point will go into your scrap pile.
I'm going to do Tula Pink's stacks. One of the required pieces needs to be 18.5" long. So I'd divide 42 by 18.5 (and without a calculator) I know I'll get two strips (total 37" which is less than the 42" WOF. With a calculator the exact number is 2.2702 strips.......................... Which would leave a scrap of about 5".
If you are using standard sized fabric ie. 42-44" this method will work NO MATTER HOW WIDE THE PIECE IS, as long as you are cutting WOF. You'd calculate a 2" x 12" piece the same way you'd calculate a 6" x 12" piece or a 12" x 12" piece.
Not to be bossy or anything--------cause I can be------but print this out and put in on the front page of your pattern folder.
Now, wasn't that easy!
