I've just been reading about what notions people want and someone really wants a sliding mat for machine quilting. Well I did too, so I googled, watched a video, and then I had a brain wave. In the bottom of my oven I have a black, non stick (teflon?) sheet that all the bits just fall off so I don't have to clean there and I thought "would it be slippy enough for quilting?". I had a spare sheet in the cupboard, so took it upstairs to the sewing machine, made a needle hole, stuck it down with painter's tape and WOW it makes such a difference!
