So, I love the Threshold but I really dislike boat neck sweaters. Would it be possible to modify this pattern to have a crew neck? If so, how would I go about doing it?
Welcome to the forum!
Look for a crew neck top down sweater on Ravelry so that you can see how the front neckline cast on is worked. It will help to use a sweater that you have as a template.
There’s also a handy book by Ann Budd with designs for top down sweater is various gauges.
It’s in my public library and it’s worth a look.
