Thank you for these replies, and for the extra suggestions
@sewmuchmore I've started looking them up - you've really given me something to ponder on there. It's always nice to have a variety of options even if it doesn't help me cutting down the list for the way home.
Now I'm wondering if we can make the route a figure of 8 and squeeze in Fabworks before crossing to the west for Burnley and leave the way home for Shipley, Skipton or...
@Surest1tch - yes, I wasn't thinking specifically of curtaining from Waltons necessarily. I've only been there once before in 2019 and that was for dance lycra of which they had a huge selection so that has coloured my memory.
@Tamnymore - we went to Fabworks on the same trip as to Waltons so I'm keen to return there too. I just wish I could say I'd sewn up all the fabric I bought from there last time.
