Started out knitting with straights, switched to circs and have never looked back. Except last summer, when I needed two sizes of needles to do a stitch pattern for a summer top. A 3 and a 5.
No problem, I thought. I’ll use my Denise interchageables with one size on each end of the cables. But the smallest size in the set is a 5.
Fortunately, I had a bunch of old straights in a vase as a decorative chotchke. But boy, it felt so weird to have those rigid pieces of plastic sticking out on both sides. (They were too short to tuck under my arm.) The job got done, but I don’t look forward to using them again.
