UPDATE: a year later, the top of the post caps have faded in the sun. It's not obvious in our setting but if you will be viewing the trellises from a height it may not be what you want. I expect the vines I planted will eventually be so dramatic the post caps won't be noticed. Another positive note, the texture on these is sufficient for clinging vines to grab hold.  ORIGINAL: These lattice panels look just like wood unless you are six inches away! My husband put them together in 30 min each (I bought five). UPDATE: Based on our experience, they will need extra support if they aren't wall mounted. (See photos.) Trellises are top heavy so we bolted them to our house with 6-1/2 ft. c-channel rods since we were running them along our property line like a fence. We found the trellises also wobbly so bolted a 1"x2" board, stained to match, to a horizontal on each. These two remedies were not difficult and were worth the trouble because the trellises are so attractive.
