bobbles

Bobbles are decorative spherical protrusions or clusters applied to textiles and accessories. They are most recognizable on knitted hats and scarves, where a yarn-based pom-pom or several smaller bobbles adorn the surface. Beyond fashion, bobbles may appear as raised stitches on fabric or as removable ornaments on bags, keychains, or jewelry. Bobbles can be constructed in several ways: yarn-based pom-poms formed by tying strands and trimming the loops and attaching them to fabric; knitted or crocheted bobble stitches that create a raised bump; or as plastic, fabric, or bead embellishments that are glued or sewn on.

In clothing, the term bobble hat (also called a pom-pom hat) refers to a winter lid featuring a large yarn pom-pom on top. Bobbles have appeared across various cultures and fashion periods, from children’s wear to Nordic-inspired designs. The word pom-pom is a common synonym in many markets, though usage can vary by region and by whether the emphasis is on the yarn-based ball itself or on a detachable ornament.

Materials and care vary with form. Yarn bobbles are typically designed to be integral to the garment and may require gentle washing to preserve shape; detachable bobbles can be removed for cleaning or replacement. In manufacturing and craft contexts, bobbles are valued for adding texture, color contrast, and a playful or whimsical aesthetic to garments and accessories.
