Start with three Pashmina-style scarves (check clearance racks for great bargains this time of year). All you need to do is to sew them together, and you'll have an easy-to-pack, warm blanket.
I found out the hard way that sewing these thin, long, scarves together is a little easier said than done, especially if you are just a craft sewer like I am. I had trouble keeping the edges lined up, even with a lot of pinning. And, much to my dismay, I found out that the scarves were not equal lengths to start with, so I got a ragged edge.
To help with the sewing, I used some fusible webbing material to fuse the scarves together before sewing:
This really helped with the alignment. Then I top stitched along the same path in a contrasting color just for fun. If I had really planned ahead, I would have staggered the scarves so the un-evenness would be equal on each end.
So, what do you think?
