We took a holiday in the Portuguese island of Madeira recently, and I was pleased to find the fabric shop Feira Dos Tecidos open (I had seen it in Lisbon at Easter but it was closed).
All 3 fabrics work well with existing pairs of purchased wool trousers - one camel, one dark brown. The second two also work with black basics and some wool mix charcoal trousers.
DBF was not impressed by how long I was gone (45 mins) as he couldn't imagine I could be in the shop all that time and was worried I'd got lost. He also didn't seem too wowed with brown based sweater knit fabric, so I have promised its Autumn/Winter wear for work!
