I (intermediate knitter) went on a trip to Paris a few weeks ago and walked by a cute store called Mes Demoiselles. I thought it would be fun to make this cardigan and tank top that I saw in the window. I can’t find a pattern that is exact on raveley, but I can see the pattern and could make a guess with a test swatch. It looks like mohair to me. Should I Frankenstein a pattern to get my sizing and then work on the lace once I have a swatch that I write down that makes sense? Do you have any recommended places to look besides ravelry?
