Lately I prefer fabrics that have a bit more interest for me whether it's the fibre content or the colours and design.
Often it costs a little more than what's generally available and takes a bit more effort to find.
My most recent buys are from from a couple of pre-order suppliers
One example is this design in a Bamboo Cotton with lycra for a knit Tshirt/Tunic top.

The shops I go to include Immanuels and Fine Fabrics at Burnley.
As I regularly visit family in London, I like to pick an area and explore fabric outlets in that area. I like Dalston Mill shop on Ridley Road but because it's rammed with fabric I only go when I'm looking for something for a specific project.
My personal general rule is to be very choosey about what I buy and it must be for a project on my immediate To Do list or if it's particularly interesting, unusual and inspiring and will become a specific outfit like a coat, jacket, dress ir an outfit in itself. I no longer buy fabric just because I like it. It must have a specific project that will be made within 6 months because I also have to sew up the stash fabrics I have chosen to keep.
I like to go to to shows like the Knitting and Stitching shows to buy fabrics from the stalls for my project list. Rosenbergs, Nicole's Dots and Stripes and a couple of others are places where I usually manage to find some fabrics I like.
