Clothing factories & manufacturers cut fabrics ready to make into garments. However at times they have excess pieces, usually Not complete garments. So we buy these to stop them going to landfill and sell them on really cheap, it's a great way to get creative or test out new fabrics. So to summarise they are pieces of fabrics. Odd shapes and sizes, different prints and plains, different fabrics eg cotton jersey, Jersey, knit, lycra, scuba etc. Some you can work out what they would have been made into, most you can't lol. Lots of customers like creating dolls clothes with them, face wipes, small items, tops for themselves etc.
