.....our neighbor had a yard sale last weekend. My "Bride" and I ventured down for a peek. I picked up some school supplies and within I found some small plastic geometric shapes. I used some of them in this pen along with Holly for a bit of segmentation along with one Aluminum slice dead center. I painted th tube white in hopes of brightening the glow of the plastic. . Something different and a learning adventure too. Thanks and be well.........Jan
