Hello! I would like to substitute some of my stash yarn in the double weave shawl. I have some Harrisville shetland, but would like to use the Quebecoise wool and some La Jolla superwash merino wool for the smaller stripes. In your opinion, would this work ok? The Quebecoise is a tad bit thicker and the merino is a tad thinner than the Harrisville shetland. Thanks for your help!

Hi! A thought that came to mind when reading your question was that the superwash wool won’t full like the HV Shetland will, so you might have some puckering where the small superwash stripes are, because they won’t shrink at the same rate. I’m planning to make this project as well with some inherited stash yarn, so am interested to see what I can come up with!

You are right on, Carrie! Using superwash wool won't give you the tighter weave structure in the stripes that you usually want in a blanket. It won't pull together at the fold if you use superwash there and give you a nice finished look. It would be worth your investment of time in weaving the blanket, to put on a small warp that combines the two in a scarf, using stripes the width you plan for the blanket. Full it the same way you would a blanket and see what happens.
