This one needs good light, but I love the transparent layers. And I'm starting to enjoy the round Gelli plate that I got at Christmas. It requires more planning than the rectangular one, in terms of composition. And also, registration is really important to keep the circle tidy. The way I do it is I mark the bottom corners of the page and the left and right edges of the circle on the mirror that I use as a base for the Gelli plate, and I use these marks to align the paper for subsequent prints.
