I really enjoyed making this shrug. It took me a little over a week and the stitches were simple enough. I wasn’t a huge fan of doing double treble crochets and would have preferred changing them to treble crochets. I used a larger hook that suggested and skipped the last row on my back square to make it the suggested 20 inches. I sewed up some of the armholes (I probably should have made them less than 20 inches) and single crocheted around them in a smalled hook to make them form fitting. I also added an additional increase row in the circular part of the shrug to have a more relaxed fit.
Very very simple and easily modified.
