I'm currently trying to remark a trail that seems to be forgotten or had very little use in the past few years. The markers that remain (different types of ribbon) are fraying or crumbling depending what material they are made out of. They are mostly tied to trees. I've started by tying up some "flagging tape" to trees in a similar manner, but I wonder how well the flagging tape I've chosen will hold up. I don't want to have to do this again next year and I'd like someone who comes upon the trail in a few years to be able to enjoy it as I have.
I wonder if anyone has suggestions for ribbons or other materials that will be resistant to sun and weather and keep their color.
The stuff I'm using is quite thin and about 3.50 USD for 300 feet (90 metre), which seems to be enough for a maybe a mile (1.6 km) of trail. I'd be willing to pay a bit more for something that would last. $35 would be okay, but $350 is too much. It also needs to be pretty quick to apply.
Additional information
There are already colored plastic fragments of old trail markers strewn around the area of the trail. Another reason that I'd like the markers to last is that I'd like not to add more fragments like this every year. Markers that fade without a trace (like paint) might avoid this also.
A few of the comments and answers mentioned terrain and temperature. The trail is mostly wooded and in a temperate climate. It's a bit rocky in places. The coldest days in the winter get down to 0°F (–18°C) and the hottest days in the summer are around 105°F (41°C). Parts of trail typically may flood in the spring.
