This square or 4 corner apron is quicktomake and perfect for the beginning sewer but clever enough to appeal to even the more experienced sewer. Selecting the coordinating fabrics is SO easy because it looks good in everything. By the way, it's very comfortable AND flattering Adjustments in size are made by the length of the neck strap on the apron 23" to 26" for small, medium, or large. Slightly more fabric is required for the apron if using vertical print fabrics like stripes or oneway vertical print fabrics like chickens.
