The fabric we buy online is exactly the SAME as you buy in craft shops. I go to craft shows note the fabric by maker Moda, Kaufman etc, most fabrics have a design name, the maker is usually printed along the selvage, I agree I like to test the "feel" of the fabric so I examine the fabric carefully make a note then go home and switch on the "On" button of my computer and order from the many online shops in the US.
Some of my favourites are Fabric Shack, Fabric Depot,<Fabricworm and Quilt Kits Online. Connecting threads have beautifull fabrics but do not ship internationally.
I always go for quality as so many hours are put into making a quilt and I always want them to look good for as many years as possible after constant laundering.
