Linda Janklow of peopleOlogie returns to the Portola Valley library with the Natural Dyes Workshop. Did you know that what you eat or grow can be used to make color? Using your plants or ours, you will squish, submerge, and stir, watching nature transform white cotton into beautiful color. Space is limited, so please register (650.851.0560 or email@example.com). For ages 9+. This program is generously funded by the Friends of the Portola Valley Library.
