I have just finished this cardigan for my three year old granddaughter. She loves it and can’t wait to wear it. She chose the buttons too. Using circular needles to make the sleeves was quite fiddly and the straight lines of the rib have suffered, another time I may have a small seam under the arm. The yarn has a sparkle which sadly isn’t picked up in the photo.
I found the free pattern on Ravelry I mentioned this website before as a great resource for those who enjoy knitting and crocheting. Although entitled Autumn Cardigan, I think it will be very suitable on Spring days too.
