That's one project I've been planning for a very long time - a very simple Rag Quilt made of old bed linen. The front and back are going to be identical as far as the colours and patterns go. Each square is made of two fabric squares 22 x 22 cm, with a 20 x 20 cm square of batting in the middle. The seam allowances will all be on the right side of the quilt, and are going to be frayed and so soft, while the wrong side will be seamless and ready to cuddle under. And it's going to be ever so cuddly because old bed linen just gives you this "homey" feeling.
