Hi, I was wondering if anyone would be able to help me alter a sweater. I am fairly new to this but I would like to put a vee at the neck in the sweater that I am making for my son. He has a very big head and would like for him to be able to wear this sweater for awhile. i would like to be able to add buttons to the vee. Any help would be appreciated. Here is the link for the sweater pattern. I am doing the smallest size. Thanks!!
