See the young man in the above photo? He’s older than you think. His wife made him that sweater. I don’t know his wife but I can tell you right now that any future argument the two of them have can be ended rather quickly by her saying, “I knitted you a Super Mario Bros. sweater vest and this is how you thank me?!” Seriously, until they die she can play that card.
People all over the internet have such a boner for this thing (understandably) that the designer has promised to make the pattern available for other aspiring seamstresseseses. Until then, you can take a gander at the list of necessary supplies and head over to Michael’s or wherever it is you buy stuff to make the coolest sweater vest in the history of clothing.
