I've shown the beginnings of my knitted scrappy square blanket on my blog before. I'm following The Coziest Memory pattern by Kemper Wray with a 46 stitch cast on and using 2.5mm needles.
I was going to mix indie dyed yarn with commercial yarn in the blanket but then decided that I'd keep the two separate and make two blankets instead. I've actually got a bit further with the commercial yarn blanket.
It's fun working with scraps of yarn from other projects, it does bring back lots of memories. There's yarn already in this blanket from the first pair of socks I knitted and yarn from socks I've knit for other people. It's such a fun project.
There's various ways in which the blanket can be constructed, with the lines which the centre double decreases make all facing one way, making a chevron pattern, or as in the case of my blanket, making a cross in the middle and then radiating out.
I shall be looking to pick up some mini skeins to add in to the blankets as well as using up leftovers from other projects but they're going to be very long term projects.
