I just finished writing up a pattern for a very simple seed stitch lap blanket, which is available here.
I made this using the new Luxury Wool yarn from Loops & Threads that Michaels has started to carry. An excellent price for 100% wool! Also, it took me quite a long time before my very mild wool allergy started to act up.
I have three more balls of this yarn in blue and haven't decided what to do with it yet.
Once again, here's the link for the free pattern.
