I frequently weave pine needles, sea grass and other natural materials on my gourds. Most of the time I am happy with the results but the pine needles always end up looking rough and ragged. One of the other issues is that when I use philodendron sheaths, over time they get very dry and fragile and do not transport well which makes it difficult for me to take them to shows and sell them. At the shows I see lots of smooth, shiny pine needle and beautiful philodendron weavings and am wondering if anyone has some tips on maintaining that smooth appearance and what kind of finish to use. I've tried one spray product but over time it started to flake off and it really looked awful. Any ideas would be helpful.
