Question: what are wof strips in quilting?
Answer: WOF. This acronym stands for width of fabric. You'll see if used often in cutting instructions, as a pattern may say "Cut a 2 1/2" x WOF strip." The usable width of most quilting cottons from selvage to selvage is about 42", though there are some wide styles at 54" to 60" and extra-wide at 104" to 110".
