I am a real beginner at this knitting lark but I have just finished knitting a patchwork blanket with some cheap wool (by way of a warm up) and now need to more on to something a wee bit more challenging, or that requires more skill/different stitches/new techniques, etc. The blanket was just squares sewn together. Any suggestions for what to do next? Must it be a bobbly hat? 
I would be very grateful for some advice please ...
(Some of the other threads have already been helpful. I've ordered a couple of books that were recommended, and found out where to get the wool).
