Ah Debbie, thank you so much!
The wool is acrylic, and slightly fluffy (a nightmare apparently!) - she tried wetting it, folding it in half and then hanging it over the shower screen with a loads of pegs down the side. Had it hanging up for 2 days but as soon as she took the pegs off it curled back up again.
I’ve suggested ironing but she’s nervous of the wool, so I did suggest she tries the steam mop and as she goes along tightly wrapping it in a towel (kind of swiss roll like), then leaving it for a couple of days to completely dry again. She’s tried adding a border but apparently that didn’t work, I guess it could be the wool type maybe.
She’s a keen crocheter and knows what she’s doing with that, but knitting is proving to be a different beast!
