Conventional wearable electronic devices include may include a watch band for attaching the device to a user's wrist. There are varieties of materials and configurations for forming conventional wearable bands. In some cases, it may be desirable to form a band having multiple layers of different materials. However, due to normal or predictable use, a composite or multi-layer band that is constructed using some traditional techniques may be susceptible to failure. The techniques described herein may be used to form a multi-layer or multi-material band for an electronic device that may have a construction that is more robust as compared to some traditional watch bands.
