  1. Hello, I love these three baby patterns. I am hoping to make them for my brand new few days old grand daughter, Martha Rose. I havent got a printer, but jotted down instructions. I am however confused because with the sweet cardigan in garter stitch there is no mention of the 2nd colour for the edging, the reason I like it so much when you look through the instructions. Please advise, thanks Alison.

    1. Hello Alison,
      I added the info to the pattern so you can see which parts are knit in the MC – main color and the trim in the CC – coordinating color.
      I hope that helps!

  2. I do not see ,instructions for the bands for the bottom left, right and back.
    Please advise – thanks

    1. Hello,
      In the pattern instructions, you will see the titles SLEEVE BANDS (CC) and FRONT BAND (CC) this is what you are looking for.
      I hope that helps!

  3. Hello,
    I am just making this cardigan but I’m just wondering about the 24 stitches left on the stitch holder and what I do with those?
    I also wanted to check for instructions on the bottom trim front and back. There is only pattern for around the neck and front sides.
    Thanks so much
