I adore vintage apron patterns. I have a large collection, and have scanned the covers of a few to use them as decorations on the walls of my sewing room. Here is a gallery of photos. Sorry for the slow load times, but I’ve included full-resolution pictures in case you want to print them.
A love 'utility' apron with large pockets
A 'hostess' apron
This is by far my favorite apron pattern cover.
Some Christmasy 50's goodness here
This shows you the condition of the original pattern envelope. The next picture shows it after I've cleaned it up in Photoshop
Lovely embroidered aprons for the man and the woman
McCall's Sample - no pattern number
The hostess with the mostess
I just love this pattern. Edging on groovy, and has the Lucille Ball lookalike model
Adorable holiday hostess aprons
Another example of pre-cleanup of the apron cover.
Definitely not meant for washing the dishes
