SEMINOLE SWEETGRASS BASKET - "Sweetgrass" baskets have been made by Seminole Indians for more than 60 years. The wild sweetgrass used in these beautiful, sturdy creations is hand-picked from high, dry areas of the Everglades basin, washed, laid in the sun to dry and sewn together with colored threads. Palmetto fiber is the usual basket base material. The baskets may take many different shapes. The Seminole Tribe of Florida.
