I don't think I could make a baby blanket in sc. I don't have the attention span.
:
The simplest blanket to make would be to make a chain the length you want the blanket to be (I usually make mine the size of receiving blankets). You'll need an even number to start with, but accounting for the chain you lose when you start to sc (you know how you need 20 chains if you want 19 sc?), you'll have an odd number.
Then, just do: *sc, ch-1, sk 1* all the way down to the end (if you miscounted or something & wind up with a chain at the bottom where you have a chain on your hook, no worries, just pick that last chain out). It's a very simple pattern, but it gives a very pretty textured look, and a more supple fabric than straight sc.
If you do want to do a blanket in straight sc, I'd suggest using a hook a size larger than you usually do for that yarn to keep it from getting too stiff.
You can also just do single crochets in the back loop only of the row before. It gives kind of a ridged look to the final product.
