I downloaded the pattern for two pillow covers last night, and started -- this is what I've done so far -- I'm using the Jamieson's Aran yarn (100% Shetland) on 4 mm needles.
Looks good -- but I think I goofed in that when I cast on, I didn't do the "knit one row" back to "finish" the cast on -- so my bottom will not match the sides -- not to worry -- I'll do the top the same, and it will become a "design feature".
My pillow will be larger than the 12" as designed -- when I've finished, I'll block and press and stand back 6' to see if I like how the pattern shows up at this tension.
I'm using my long dp needles and knitting belt -- I really like how this works and will be knitting my next fair isle using these traditional tools. I just have to decide on which one to knit -- it should be the Alcea Pullover from the new Simply Shetland 3 book -- because I think this is a gorgeous design! But then again, I really liked knitting Erin, just for me for no other reason......hubby says, why not start two -- gotta love a guy like that!
