It appears I've found a few uses for some of the not so normal plastic pieces - including newspaper sleeves. The grey material is actually rolled pieces leftover from the grey ironed sheets I used in the Capelet post. The tan is the standard Fred Meyer plarn, but with the density it produces almost a reed-like mat. Both of these were created on a basic 2"x2" square frame that is 22"x22" and nails spaced at 3/8" gives flexibility for the dense reed matting or skipping for the rolled mats.
