Too complex for just words. Please show it. Several view maybe.

Don't have pics right now unfortunately. Basically if you face my backyard (standing on the patio facing the back),the property line to my left goes at 45 degree angle until it ends at a point in the left cornerr which has the visual of appearing 1/2 way into the my yard. Now picture an ugly 4 ft fence on that line. I need to cover it but can't use huge bushes/hedges as it is narrow and claustrophic to start.

I'll try to work on pictures later...thank you!

What kind of fence is it? Chain-link, wood, vinyl? Are you friendly with the neighbors?

If it's chain-link, you can get slat things that insert into the fence and does make them look nicer, or at least recede from view somewhat. If it's wood, maybe you can paint it. Both of those options would require chatting with the neighbors and getting approval.

If it's vinyl, I think you might be stuck with it. Although, I suppose there's some paint out there that you can use.

If it is by chance a chain-link fence,check out the link below. I think these people came up with a fantastic and very creative solution to turn their eyesore into something beautiful.
