This keyboard intarsia is an original design (sorry, no pattern available) that I made for my SIL who is a musician. It is a knitted version of the D50 which was his first synthesizer and remains his favorite today. This sweater is about 5 years old and knit from Red Heart Soft yarn. It has been washed innumerable times, bleached and always machine dried. The changes in yarn texture are from washing in too hot water and drying in a hot dryer. He is a better SIL than clothes washer. Red Heart can take it. The look on his face comes from trying to stay awake after working a 16 hour night shift. One minute later and he was asleep.
