Last night I knitted 3 more hearts and started a 4th heart. I am using this pattern from Lion Brand: http://www.lionbrand.com/patterns/BK4K-0602001.html?noImages=
However I am knitting from only one strand of yarn using size US 8 knitting needles. Two of the hearts are made using red Lion's Brand Homespun and the others are made from the standard acrylic yarn in white. I am making small pillows for my toddler for Valentine's Day. I might embroider something on the white hearts. The white hearts are slightly smaller than the red ones. That just goes to show you how 2 different yarns can result in 2 different sizes.
