Here's a picture of my drying frames. I've got two of this large size which can take a canvas of up to 81cm (32 inches) wide, but any reasonable height, say up two a metre and a half. I'll make a few more of different sizes for smaller panels and things. One feature of this design is that several horizontal T bits can be bolted to the main bar, allowing a two or more smaller pictures to be held without the need for a whole new rack.
In other news I've decided to repaint the Wales picture and have developed a new composition. There aren't many differences, but the new one will be smaller. I'm not happy enough with the other picture and will destroy it, or possibly cannibalise parts I like to make something new.
