  This work presents a novel interactive system for simple garment composition
and surface patterning. Our approach makes it easier for casual users to
customize machine-knitted garments, while enabling more advanced users to
design their own composable templates. Our tool combines ideas from CAD
software and image editing: it allows the composition of (1) parametric knitted
primitives, and (2) stitch pattern layers with different resampling behaviours.
By leveraging the regularity of our primitives, our tool enables interactive
customization with automated layout and real-time patterning feedback. We show
a variety of garments and patterns created with our tool, and highlight our
ability to transfer shape and pattern customizations between users.
