I found a bag of pink 2 ply that I bought somewhere. It had originally been coned yarn but its previous owner had wound it into cakes. 2 strands of pink combined with one of white 4 ply and one of lilac 4 ply gave me roughly a chunky yarn equivalent, which, when knitted on size 4.00 needles gave a pretty and dense fabric suitable for mittens.
I had enough of each of these yarns to be able to crochet a hat and scarf suitable for a young girl. This made hat number 5 for this year. I thought that an earflap hat would work well with chunky yarn.
I have to confess that I have already bought some more yarn this year (obviously 20 kilos is not a sufficient stash size), but at least this month I have used up more than I have bought. A large yarn retailer sent me a voucher for £5 off a £15 spend, and also threw in free postage, so I succumbed and bought 700g of James Brett Baby Marble. The flip side of stash counting is that you realise where the gaps are in the yarn range you have, and I had no baby variegated yarn. This just had to be remedied, I am sure you will understand!
