The felting process has roughened the surface of the panels and obscured some of the color and detail. To make the surface smooth for stitching and other mark making, I carefully shave the front and back of each panel.
This really makes a big difference in the surface texture. Look at all the fuzz I created. I may save it and use it in another piece but I'll probably toss it. I have yet to do anything with any lint I may have saved through the years.
Here comes da _____. No I can't say it!
Using a steam iron, I block the front and back of the panels. This process smooths them even more and makes them more rectangular. It's easier to work with dry panels.
