I have a couple of pairs of pj bottoms from Tesco made from fleece from years back. I’d like to make a few pairs but I am not sure about which fleece fabric to buy. The RTW ones are sewn from a smooth, flatter fleece rather than the higher loft, fluffy fleece (but that may be due to their age and umpteen washings). I don’t actually wear them to sleep, just lounging around the house. Any pointers on suitable fabrics? This may seem obvious but when I search for fleece fabric, there seem to be different types, not to mention prices.
