Thanks for contacting me-This was my first published pattern, and everyone that test knit my project has been knitting with me for ages and understands what I mean as opposed to what I say/write! I am flattered that you chose this particular pattern.
The bag is should look like a large rectangle, a large triangular shape, and the strap. Fold the rectangle on the turning ridges, so you have something resembling a cereal box minus sides. Pin the strap to the bag using clips, and crochet (or whipstitch) from the bottom front up, over the two short flaps bringing them together at the center corners so that they meet in the middle, and then continue on down the other side. Repeat for other side. Fold the triangle on the turning ridges, lay it on top of the bag, and begin crocheting (or whipstitching) the pockets to the bag starting at one top corner going down, across the bottom, and then up the other side.
Does that sound better?
