No sooner than I said I'd probably never crochet another blanket, I happened across the Ravelry 2012 BAMCAL (Block A Month Crochet ALong) group and, before I knew it, I'd clicked 'join'!! After all, how hard can one block a month be, right?
Weak-willed .... I know!!
So, how did one block a month turn into the four blocks you see above?
There's the official 12" block for the month (top left) and the 6" block (top right) for anyone making baby blankets, plus an optional 12" block that we voted on (bottom right) and then someone posted a new design in one of the discussion forums asking for testers (bottom left). You pick and choose which ones you want to do; some keen people have done multiples of each block. I'm just doing the ones I like, so some months I may just do one block or even repeat a block that I've already made in another colour combination.
You're probably wondering by now how my 6" and 12" blocks are all roughly the same size (and 8" at that!)! I'm using DK yarn and a 4mm hook, so my blocks were always going to be small and I added some rounds to the 6" block to bring it up to the same size as my others.
By the end of the year I should have improved my crochet skills considerably... I may even be able to dispense with reading my crochet book to work the stitches out at the beginning of every pattern!! And I should have a nice, colourful blanket!
