This pattern is for an Aran Cardigan using a simple pattern repeat of only 4 rows. I have given fit sizes of 12/14” and 16/18” but please measure your bear and check your tension to ensure a good fit. As this is such a small item any variation can make a huge difference to the size of the finished cardigan.
the models are my granddaughters build a bears.

I have given an approximate weight of yarn for each size but, depending on yarn used the larger size may take over the 100g. Also if using budget Aran, which can be thicker than normal, the item may be larger.
I used King Cole Comfort Aran which is a good quality soft yarn and a budget yarn for the larger size.
