So far it is about 13 cm square (about 5 inches) and I am going to finish it off by edging it in another shade of blue. I'm also going to make a mini 'granny square' patchwork blanket as soon as I get some more 2ply wool in different colours.
Next, I decided to make a miniature crochet monster:
She is 9cm / 3.5 inches tall (not including tufty bits) and her name is Delilah Axolotl (on account of her tufty 'gills' and the fact that axolotls are my new favourite creature after seeing one on QI last night). My usual woolly monster puppets are about 10-14 inches tall, so Delilah is small enough to be a doll for one of them.
I have not tried crocheting with single ply yarn and a 0.6mm hook yet. To be honest I'm not sure whether it's really necessary to go that small for my purposes - I'm never likely to work at 1:12 scale or smaller!
I have also discovered possibly the most amazing discount yarn supplier in the world. For anyone who likes doing any kind of needlecraft or textile work and can feasibly travel to Heywood (near Bury/Bolton in Lancashire, northwest England) - it is essential that you visit this place!
The shop is only open to the public on Fridays 10am - 5pm (other times by arrangement).
They have an old Co-operative store which has two rooms literally full, from floor to ceiling, of thousands and thousands of part-cones and balls of surplus yarn in every variety imaginable. Wool, cotton, linen, silk, synthetic, metallic, mohair, cashmere, alpaca all in every thickness and colour you could imagine. I'd estimate that most of the cones have 200g-1kg of yarn left on them, and you pay for them by weight. At least half of the yarns are priced as low as 99p/100g!
They have even supplied Cosgrove Hall with yarn for mini-knitting of puppet costumes.
I bought a ball of black and a ball of white acrylic doubleknit (always handy), a cone of turquoise mohair (great for fuzzy monsters), a huge cone of burgundy pure wool doubleknit (or four-ply, it's hard to tell) and some periwinkle blue 2ply and single ply green wool for mini crocheting. The can of 7up is there for scale. I am going back again next Friday to get more colours!
