Was hoping that flexible in all directions front loop only in the round slipstitch crochet would enable these to stay up on their own - Fail :( Tried different ribbings at the top but did not find one that stayed up.

Yarn In Back (YIB)
Yarn Over (YO)
Front loop from bottom to top/front to back with YIB and YO (F)
Increase = F into st below current stitch, F into current st (Inc)
inverse Back loop from bottom to top/back to front (iB)

Ch 24, form circle, back bumps in, F for 18 rounds. (24)
*Inc, F5 *Rpt around. (28)
2 rounds even. (28)
*Inc, F6 *Rpt around. (32)
18 rounds even. (32)
*Inc, F7 *Rpt around. (36)
7 rounds even - ran out of Maroon. (36)
13 rounds even - switched to Charcoal grey. (36)
*Inc, F8 *Rpt around. (40)
10 rounds even. (40)
Last round: From the inside st below, YIB, iB, YO

After wearing for a couple of days, my ends were popping out - need to find a systematic way to weave in ends for F in the round.
