The whole thing takes under an hour to make if you're used to sewing. How much less, I don't know because of my Mommy Sewing Method... you know the drill! -Cut, iron, start stitching, pull out lunch for everybody, sit and eat with everyone, sit and sew, stop to get the Table-Clearer child back to do his job, iron, sew a little more, stop to get the youngest child down for a nap, sit and sew some more...
You could use the terrycloth dish towels for an extra-absorbent apron. There are some cute dish towels sometimes!
