How many yards of fabric you need to make 8 cushion that measure 24x24?

Well, since cushions have 3 dimensions (width, length, & height) I'll suppose the third dimension (height) to give you an idea of how to calculate the fabric needed. Keep in mind that we're covering six sides: front, back, top, bottom, left, & right. For example,let's assume your cushions are 24" wide by 24" long by 6" high. To determine the width of the fabric needed per cushion we need to add the width plus half of the right and half of the left or 24" + 3" + 3" = 30" and to that we'll add 2" seam allowance for the right seam and the left seam or 30" + 2" + 2" = 34" total width. To determine the length of the fabric needed per cushion we need to add the length x 2 for the front & the back and the height for the top & the bottom or 24" + 24" + 6" + 6" = 60" and to that we'll add 2" seam allowance or 60" + 2" = 62". This will cover your cushion like a pillow case that is sewed (or zippered) shut, so, you'll have no seam in front but seams on the top, left, and right sides. So, the piece of fabric you'll need for each 24" x 24" x 6" cushion as assumed above is 34" x 62". If the height of your cushions is different than the 6" I assumed, you need to adjust the calculations for top, bottom, left, & right. Also, the total yardage required will depend on the width of the fabric that you choose.
