The Pillow requires 4 skeins of Alpaca Heather. The MC is one of the undyed yarns and then one skein each of the minis. There is yarn left over if you want to adjust the pattern to be bigger.
I love Alpaca Heather for this kit. It is a gorgeous yarn that is just the perfect amount sticky for Fair Isle colorwork but soft enough to want to wear - or rest your head. The pattern was written to support a class on how to work Fair Isle, Intarsia, and duplicate stitch. The pillow is worked in one piece with no seaming!
