Crocheting the edges, cutting open: I am beginning to evolve into opinions about when steeking is worth the extra work of all the crocheting, and more importantly, the hassle and lack of ‘couture’ from the bulk and sometimes flapping cut edge on the inside/backside.
Rule : Steek most definitely for patterned knits (both textured relief motifs and stranded color.. yes!), but, for solid backgrounds, especially of anything worsted weight and heavier…um.. I”ll leave it as a very reserved ‘maybe not’ . My preference only. For these vests, I think maybe would have been better to not steek, as the bulkier worsted weight yarn is quite cumbersome on the backside of the front and armhole openings. Of course, I could have used a different and finer yarn to crochet the steeks, but I didn’t have any around. Rule reconsidered : Use finer yarn to crochet steeks !
And who said it had to be the same yarn? Also, why not crochet before washing and blocking, then after all that, cut steeks ?
Rule : Use finer yarn for steeking. When purchasing heavier yarns as worsted or bulky weight, purchase also a lighter weight yarn in similar fiber, and matching color, for crocheting and stitching down the steeks. Oh, and for sewing on the buttons !
