The Arnold Arboretum offers a two day workshop on Saturday and Sunday, September 10 and 11, from 10 – 4 on Botanical Printing on Fabric. Transfer images and anatomical details of plants onto fabric by inking them with textile paints and thickened dyes. Learn how tools, plants, textiles, inks, composition and color can be applied to produce diverse results, from exquisitely detailed to boldly expressionist. You will print many samples, learn to fix them for washability, and leave with handouts and notes. Limit 12 students. Fee: $150 Materials: $25 payable in class. Offered with the Eliot School, where the class will take place. Leonore Alaniz, textile designer, instructs. Register at www.arboretum.harvard.edu.
