Odd needles. Remember that? Didn't everybody's mother knit a vest with this technique in some kind of nasty angora/acrylic blend to wear over a polyester blouse?
This Rowan Cotton Rope worked with one 6mm needle and one 20mm needle.
After having struggled with a student's first drop stitch project in a recent class (not a good idea in a highly textured yarn), this seems like a good cheat.
Am noodling on this for a summer design.
