Bladderwrack is a variety of seaweed, and the reverse seaweed rib in Barbara Walker's Second Treasury of Knitting Patterns reminded me of seeing it on beaches in Suffolk as a child. I got this yarn when Chris' Needlecraft closed down in 2009.
Pattern: My own design
Yarn: Artyarns Ultramerino 4
Needles: US1.5 (2.5mm)
Duration: 14th January to 13th February
Ravelry project: Lilac Bladderwrack socks
These came out slightly looser than I like, but are perfect for around the house as we have a "no shoes" policy. The yarn requires hand washing, which I wouldn't normally use for socks, but it's squishy and plump and nice to work with. The stitch definition is fantastic and it rarely splits. I found a few places where I'd only caught one ply, but it was easy to drop the stitch down and fetch it.
