Thank you; I really just winged it. The "bumps" (rolls) give me assurance of grip; I was looking ahead to when I would be using this with gloves this winter.
First, I ended up using just one 16-inch size US 1 circular and knitted back and forth (I would have knitted it in the round, but I couldn't find the other needle; could have used DP needles, but didn't want to.)
Long tail cast-on 62 stitches and slipping the first stitch of every row (easier to sew later), begin reverse stockinette (purl right side, knit wrong side) 8 rows. [This makes the first "bump"]
Then changing to "regular" stockinette (knit right side, purl wrong side), this is also the first decrease row: knit 29, k2tog twice = 60 stitches. Continue knitting for 7 more rows (8 rows total).
Change back to reverse stockinette and do 7 more rows [Second "bump"]
Change back to regular SS and do 6 more rows.
Then 8 rows of garter stitch (knit every row) [makes third "bump"] ----why I changed, I have no idea:teehee: )
Final section is 10 rows of regular SS; decreasing on the last row: knit 13, k2tog 4 times = 56 stitches.
Bind off tightly ; if you leave a long enough tail, you can use it to sew the sides together. Weave in the ends.
So that adds up to about 47 rows in all. Actually had to sit here looking at it to know what I did----I really did just go for it. And if I find my other needle, I'll be doing it again in the round.
Good Luck and let me know what you come up with.
