I was a little disappointed when I realized the Singer 155 came with only 5 punch cards (plus a couple the owner had punched). It's true, the 20+ cards with the Singer 327 were a little overwhelming, but there should be a happy medium! However, I'm having a lot of fun with what I do have so far! This is one area where hand knitting and machine knitting really differ. With hand knitting, you're more likely to get bored/tired of a stitch pattern after one project, because it's what you focus on. It's one of the primary reasons to knit whatever it is you're knitting and takes a lot of brain power. However, with machine knitting, it takes very little brain power to knit a stitch pattern. Put in the card, get the yarns in the right feeders, and off you go. The real work is in the pattern prep and swatching. Also, with MK, if you're going to commit to punching a punch card, you want to make sure it's a pattern you like, and probably re-use. For the small hat I made, and the current obsession I have, punching new cards seems indulgent. So, I'm having fun re-using the same card over and over!
This is the pattern in it's most basic form: (The Fair Isle pattern on the right half) My biggest complaint is that each band is overlapped with the one before it so when you change colours, one of the repeats gets gypped.
