Trees on First Street between Maple and L Street in downtown Livermore have been dressed in sweaters. The Bothwell Arts Center sponsors the Tree Sweater Forest that comes to Downtown Livermore each Fall. Area knitters and crocheters work to create this whimsical fiber art installation. The tree sweaters were donated to Valley Humane Society of Pleasanton as comfort blankets after their time on the trees. The trees will be wearing sweaters through 9 a.m. Fri., Nov. 18 (Photos - Doug Jorgensen).
