I expect it varies depending on the store, but a place near me has things like remnants and ends of rolls, upholstery fabric sample books, offcuts of things like leather (the bits left around the edges after the pieces are cut out) and the ends of elastic and lace rolls that are too small for manufacturers to be bothered with but perfect for home use.
Thank you. I definitely need to keep the work more centred - even without subtitles I was moving out of frame a bit on a few occassions. It’s unfortunate that the default subtitle locations don’t seem to be changeable, but if you are on a computer (not on mobile) you can drag them to a different position.
