Saw a photo of this project in a knitting magazine and it looked interesting because there is no sewing up to do at all - you join in the spiral at the end of each row as it grows. Decided to try it with all the oddments left in my stash from various baby and child items; although the yarns used are all DK they are different blends - some man-made and some natural. It doesn’t seem to matter at all. Pleased with the way it is knitting up and a great project to pick up when there is not much time as every row is ten stitches. It really is quite addictive to work especially as I want to know how each different colour will look.
