Blocking a shawl

Hi. I have just finished knitting a shawl in a fairly fine yarn and it is curling round the edges. I don’t normally block my work but this time I will have too. I don’t have the space to lay it out flat in one piece so so will it work if I fold it with the edges together and block it like that?

Yes, that should work. Make sure that the lower half of the shawl is pinned out if you’re going to use pins. I had to do it for sweaters knit in the round and it works.
