Color / Needed / Can get from 40" wide fabric / yardage for 49 blocks
1 (red) / 3.5"square / 11 / 17.5" (1/2 yard)
2 (blk) / 6.875" square / 6 / 54" (1 3/4 yd)
3 (gld) / 4"x11" / 3 across (4" strip) / 68" (2 yd)
/ or 10 lengthwise (11" strip) / 55" (1 5/8 yd)
4 (crm) / 3 7/8" square / 10 / 20" (5/8 yd)
These are minimum measurements, as indicated before. Add in a quarter yard for the oops factor( :oops: I usually make a mistake or two), and more if you might want one of these colors for the border.
Yes, when you get the total number of inches needed, divide by 36 to get the yardage.
I wish you the best in your endeavor!
