I’ve been churning out beanies by the bucketload.  All are from the same pattern – the Divine Hat – and they’re all crocheted in Lincraft Cosy Wool.  The yarn is in 100g balls and the hat takes about 3/4 of a ball.  I’ve used a 5.5mm hook (5.00mm for the ribbed bands) for all of these, and with this yarn and following the instructions as written they are a small adult or child size hat.  First up, one beanie for each of my cousin’s three boys:

then a couple more for my two girls:

and I’m currently working on more for Handmade Help.  I modified the pattern to make a toddler-sized beanie for Stella by starting with 13 dc into the ring, instead of 15, and did six instead of seven rows of the 4 dc clusters.  I’m going to upsize to a larger adult size a similar way – I’ll start with 16 (or 17) dc into the ring, and maybe add an eighth row of the 4dc clusters.  The yarn is nice to work with and comes in a great range of colours, plenty of solids as well as the prints that I’ve used.  I know this pattern off by heart now… each beanie takes around 2 1/2 hours to crochet.
