Update - - I made another apron using this same tutorial (for me this time!) and talk about it here: Full Apron Again
And I used a pattern and made one for my sister-in-law here: Inspired Apron
I cut my pieces as follows, but then adjusted them later - this is up to you - you can hold pieces up to yourself and see how you'd like them to fit. Here's where I started, measured in inches: Bottom 28 wide by 19.5 long; Top 14wide by 9.5 long; Waist (cut 2) 28 wide by 3 long; Ties (cut 2) 28 wide by 2 long; Top Trim (cut 2) 14 wide by 2 long; Pocket (cut 2) scrap fabric whatever size; Neckband, cut to taste (I think mine was 4 inches long and however wide to make it all the way around my neck and hold on to the apron).
