Still workin on the first cup, too! LOL! Okay, surely two heads are better than one… your multiples are just that, when you determine how long you want the shawl, for example and DON’T take this number as a good shawl number cause I’ve never made a shawl…
Feather and Fan can be 11st or 18st multiples… you want your shawl to measure (example only!) 45".
45(desired length) X 4(guage/sts per inch) = 180(estimated sts. to cast on)
180(est. sts) divided by 18(pattern stitch multiples) = 10(repeats you will have of the pattern multiples)
And you may need a border, so add those sts. to the 180…
Hope this helps! Mary
