ok sounds like normal grooming to me, I wouldn't be to concerned about it. When you said mesh wire I mentally see metal wire. If it's plastic or pvc coated it's fine.
The material safest for gliders is anti pill fleece. Most other fabrics have hazards, some fray which causes loose threads that can get wrapped around toes, some nails get snagged and stuck causing toes and feet to need amputated. Yarn rope and other woven,spun type materials have the same dangers.
not sure what kind of papers you are using on the floor, but some newspaper inks may cause an allergic skin reaction. Some of us use scrap fleece on the floor of the cage or as tray liners it's considered a safer option... Just something to think about
Homemade toys and accessories are fine, many of us do that but please ask questions to see what is considered safe and what isn't so you can make the best decisions about what you put in the cage. It might just save your gliders an injury or illness and you a vet bill in the long run.
General safety things
nothing with a hole smaller than 2 inches, or to small for your hand to fit in.
no loose or exposed threads or stitches
no metals like you see on bird toys, metal chains, d rings, hardware etc...
the list is really much longer than this and I'm sure others here will gladly add on it. Their are some groups on facebook that focus on safe glider toy making, supplies and where to find things if you interested let me know n I'll post some links for you.
