I have that pattern did not realize it had a zipper have not made it yet though, I have done another pattern that was suppose to have a zipper and I did bands and put buttons on worked out perfect and fits my grandson very well. I pick up the stitches and did the band sideways and made it a wide band work perfectly it did not make much of a difference.
Thank you - that is exactly what I would like to do with the bands - glad to hear it didn't alter the size too much. It took me a while to realize that there are 2 versions to the pattern - one with a zipper opening and the other is a hoodie sweater with no openings!!
