I knit it up in less than 10 glorious hours! This was such a fun knit and I am thrilled with the result. I knit it up using Bernat Satin in a cream colour (I have so much Bernat Satin in the stash...it's top of the line Zeller's yarn!). Anywho, I knit it on US7 and, like Sam, I also knit it in two separate halves (13 pattern repeats on each side) grafting them at the centre so that the ends would match. Bonus, I love the flowery pattern created by the graft-line.
It is only after I had completed it and started looking up how this blocking thing works anyway (would you believe I've never blocked anything in my life before) that I learned that acrylic is apparantly "unblockable." Imagine my horror! There were some ramblings here and there about killing acrylic (which frankly sounds too violent - afterall, this was a satisfying knit) and others about steam blocking by hovering a steaming iron over the garment (without touching it) and letting it cool and dry before unpinning and handling it.
I tried the latter. Not only was it quick, but the results were terrific (the pic below shows the scarf half blocked - I didn't have enough pins to block the whole thing at once). The Bernat Satin softened up considerably to near cashmerey goodness and the pattern really opened up notwithstanding the gained 1 1/2 inches in the width of my scarf and an extra foot in length. My finished scarf is 7 inches wide by 60 inches long.
Well that's another Christmas gift down. This one for my mother. I think she'll love it ;0)
P.S.: I found that writing down each row of the pattern on a separate index card and flipping as I got to each row minimised frustrating screw-ups. Will definately do that again in the future for pattern repeats. Just one of the many tips that I picked up by reading this thread on Craftster.
