It was a pretty quick make. I semi-followed the instructions during contruction. The front pieces are sewn together along the curved edge, then the same with the back pieces. Then the bias tape is applied to the outer edges. I purchased a few metres of this stuff from Sew Me Something. It has this added lace detail which definitely makes the final result. A quick search on Etsy for “crochet double fold bias tape” brings up a bunch of online suppliers, unless you’re in the area and can visit the store in person.
