The arm warmers have arrived already! They seem very well made - thanks a lot Matt

.
I agree that they are a largish medium size which suits me because my arms are a smallish-large

.
I've got a pair of large arm warmers but they don't have grippers and tend to slide down. I have another pair which are a genuine medium and they are a bit tight since I put on weight, but I'm keeping them for when I get slim again.
I didn't catch the post office today, but I'll get that Big Mig book in the post to you on Monday.
