In shrewsbury (about 13 miles ish from telford) we have a few LYS
There is RKM wools, based in shrewsbury town centre (not far from the bus station), wedged between a paperway and a yates winelodge. The shop is very long and narrow and has all kinds of yarns from wendy and some regia, patons and all sorts....
But there is also the RKM warehouse outside of the towncentre in the Battlefield estate. I think its opposite the new driving standards agency office, I havent been there so cant vouch for that (and my geography is rubbish!). Staff arent well up on yarns etc, but if you know what you are looking for you can find some good yarns and good prices too.
Colourmart is also based in shrewsbury. You'd have to contact them privately to arrange a time to pop over but lots of cones of yarn to look at!
