How Pattern Matching Affects Your Fabric Yardage

I used to think pattern matching was optional — just line it up roughly and no one will notice, right? Wrong. The first time I made curtains with a bold floral print, the pattern was off by two inches between panels. It was all I could see every time I walked into the room. That is when I started taking pattern repeats seriously.

The fabric repeating pattern calculator works on a simple principle: each piece you cut needs an extra "repeat unit" to allow for alignment. If your repeat is 6 inches and you are cutting 4 matching pieces, you need 24 extra inches of fabric. The calculator factors this into the total, adds your waste percentage, and rounds up to the nearest quarter yard.
