The Pebeo Arty's Easy Fix Stretcher Frames allow you to stretch silk and other textiles quickly, safely and easily. The ASF 1 frames make for easy stretching before and during painting and can be adjusted to fit either standard or special sizes up to 37x37 inches. If a larger size of frame is required, the ASF 1 stretcher frame can be extended to larger sizes from 18x77 up to 45x45 inches maximum using the ASF 4 Extension Kit. The frames, made from very durable plastic, are completely washable using a damp cloth. Easy Fix frames come with easy-to-follow instructions along with a black nylon bag for carrying and storing and 16 suspension claws which simply hook through your scarf or fabric. Additional claws also available separately.
