I have a friend who is having a baby and I want to knit her a baby blanket. I've done smaller items before but never a full blanket. For a pretty easy pattern (I wouldn't undertake a complicated one) how long has it taken you in the past to knit a standard sized blanket? I just need a ballpark so that I can decide whether to do it or stick to a smaller item. Baby is due in a couple of weeks and I want it to have it ready for her immediately after.
