The Take It Easel is a Gloucester-style easel that was used in the Gloucester, Massachetts area in the early part of the 20th century. It is ideally suited for working on large canvases outdoors. It is flexible enough to also let you work on small canvases.
With the help of a carpenter in China, I made a large palette that I could use with this easel, which gives me the largest workspace possible.
I can also use it as a board to attach loose linen to, when I need to keep the weight of my supplies down.
