Nearly a century old history, Oak Park Art League has colored the community by cultivating and sharing the work of local artists through instruction and exhibitions. During a glass-fusing class, students acquaint themselves with the included materials with deep, ritualistic curtsies before instructors launch into a technical demonstration. Students choose from projects including an ornament, sun catcher, or free-form picture frame, and proud craft parents are free to tote their polished progeny home upon completion.

Mosaic-making classes require a slightly more intricate approach, necessitating instruction that stretches across a pair of two-hour sessions. Instead of haphazardly shattering glass with a well-flung snow boot, students learn to carefully break panes into a palette of reusable shards. Fragments are then reassembled in creative shapes on either an 8"x10" picture frame or as a wall mosaic.
