The Arlo Track Jacket is the perfect lightweight layer you can wear on its own in the spring or fall or under your winter coat on colder days. It comes in 3 length options, is sized XS-7x, and is a unisex pattern as well! Practice your seaming techniques on knits and learn how to install a jacket zipper. If you are pretty comfortable with your serger and would like to use it for this class I am fine with that. Just let me know in advance! Otherwise, all sewing will be done on a regular sewing machine.
