I "finished" this apron in January, but then had to go back and re-adjust the front so it didn't gap. I took in a 1" dart at the top of the sweetheart neckline and strap join.
The pattern is a mail-order pattern from... the 40s? There were several mail order services that provided patterns from the same company, possibly called Reader Mail. This particular one was from a magazine called Hoard's Dairyman and is 2299.
The fabric is from one old curtain (late 60s, early 70s) acquired from home over the holidays. I love the fabric. The trim is pretty darling, too. I now have all the curtains and am plotting what to do next. I'm thinking "quilt".
I lengthened this by 3" because I need more coverage. It's still too short. Have you ever gotten peanut butter on your knees?
I modified the shoulder straps to instead go around my neck. After having an apron with crossed straps, and straight straps, around the neck is most convenient for me. The shoulder straps needed an additional 4" (!) taken out of the back.
If I made this again, I would probably fully line it, ie make two aprons, sew them together like a pillow case, and turn right side out, instead of hand sewing all that binding around ALL THE EDGES.
