We really wanted to find a way to make something very useful out of scraps of sport weight yarn! Here it is. The cutest buttons ever! You can also use baby yarns too. This is a good button to have for sweaters, as they will be washable. Decorate a babys sweater or top with rows of these buttons. Make a circle of buttons in flower shape and add to purses, totes, and hats! You will think of many uses for this. Uses knitting needles, US # 1, but work goes fast.
