Knitted Plant Hanger
I did this (my first design, bear with me) after coming up empty on pattern searches for knitted plant hangers. Pots come in all shapes and sizes, with different tapering angles. You will want to customize as needed to fit your pot (I recommend you suspend the pot in your knitting periodically to get good “as-hanging” measurements).
Yarn: 1 skein of hemp, cotton, or other non-stretchy fiber (yardage varies with pot size but you should have plenty)
Needles: size 15 double pointed needles (DPNs) and size 15 circular needles, 16" … or use longer circulars for magic loop (in which case you don’t need DPNs). Use a smaller or larger size if you want the mesh to be tighter or looser, as you like. Note: If you use the DPNs and shorter circulars, start the base on DPNs and switch to the circulars when feasible. The i-cords are easier on DPNs, but you can use a circular if you like.
Base (follow pattern until your base matches the base of your pot – then purl the last round):
Cast on 6 stitches, divided on 3 double pointed needles (or halved for magic loop). Join.
Round 1: (K1, YO) (12 sts)
Rounds 2, 3, & 4: Knit (on Round 2 knit into the backs of the yarn overs to close them up a bit).
Round 5: (K1, YO) (24 sts)
Rounds 6, 7, 8, 9: Knit (on Round 6 knit into the backs of the yarn overs to close them up a bit).
Repeat from Round 5 as needed until your base matches the base of your pot.
Last Round: Purl.
Round 1: (YO, K2tog)
Round 2: (K2tog, YO)
Repeat rounds 1 & 2 until you have your desired length for your pot.
Note: You might need to increase if your pot tapers out a bit. Increase between rounds 1 and 2 by doing the yo and k2tog to complete round 1, but before passing the k2tog to the right needle, knit into it a second time to make the increase. Yarn over. Then proceed to round 2 in pattern with k2tog…
When you’ve almost reached the desired length, knit two rounds, knitting into the backs of the previous row's yarn overs to close them.
Bind off using sewn bind-off (http://weebleknits.blogspot.com/2003/05/stretchy-bind-offs.html).
Suspend your hanger from three evenly spaced points on the base. At each point attach two i-cords twisted together. Therefore, make 6 i-cords of equal length – whatever length you desire, accounting for stretch. (I-cord tutorial: http://www.knittinghelp.com/videos/knitting-tips) Twist i-cords together and attach to base. Attach all i-cords at the top to a ring of your choosing or tie directly onto hanging device.
