I finally knit a Summer T for myself. It was a fast knit since the yarn took US No. 8 (5,00 mm) needles. It was knit top down. For the neck edging, I attached a simple I-cord. While the bottom and the sleeve edgings were made of a 2 knit, 2 purl with the 2 knit stitches crossed every fourth row. The yarn was in my stash, almost forgotten. It was quite inexpensive and on top of it, I got it on sale. That's why I'll forgive Plymouth for the many knots in it.
