Do pillowcases have to be so exact? Even my purchased pillowcases are slightly different sizes. Shrinkage and all.
But I have a wonderful ruler that the BOM teacher suggested we buy. It has a yellow thing running the length of the ruler that you snap on and off and sets to exact measurements. Somehow this teacher likes the cut things in 1/8ths or 7/8ths. I haven't figured out why but I like her quilts so I bought the ruler and it really works and is so accurate. Can't waiting until February when the new BOM starts.
