Cap Sleeve Vest Pattern by The Assembly Line


The ultimate layering piece with an easy fit for many body types. 

Cap sleeve vest works as a vest, jacket, cardigan, blazer and more. It has a straight shape, features hidden front pockets with large flaps and snap buttons for closing at front. 

The pattern includes both a lined and an unlined version.

The vest is not difficult to sew and can be transformed from skill level average to easy in no time if you skip the lining and perhaps use sew-on snap buttons, or no buttons, for the first one.


This is a multi-size pattern that comes in two size ranges, including either XS-L or XL-3XL. The traceable patterns comes carefully packaged in an envelope together with step-by-step sewing instructions.
