Does anyone collect art? What is hanging on your wall?

So I have been asked to help hang a painting = 110cm x 85cm.
It is framed and heavier than I expected. It has a taught nylon string straight across the back with some brown tape.
Not being an art expert what hanging system do you all use / what do you recommend. This has a wooden frame so would be easy to change. At home I use wire and I recall one picture I put up has a locking system / two metal plates (which were a pig to drill and line up) … but it is not falling off when the string breaks ;0)

I was thinking to try the French cleat or something similar. It looks sturdy and this picture will hang above a stairway so a long drop if anything breaks (hence why they asked for help).
Anyone used this type of thing?

These worked well for me at home but have not found them for sale lately. .

Solved…. I think … not exactly the same but I have gone for a keyhole bracket system… will see how that works out.

Love art and visiting art galleries but don’t own much
Here’s a few

On my wall, I've got a mix of pieces from local artists and some prints I found online. I'm a big fan of abstract art - there's something about those vibrant colors and intriguing shapes that just draws me in. I came across an amazing abstract piece at https://www.artworks.ae/Abstract-Wall-Art that really spoke to me. It's now the centerpiece of my collection, and I can't stop staring at it!

Hi everyone,
I love seeing what others choose to hang in their spaces - it always sparks new ideas for me! Right now, my walls are a bit of a mix: I’ve got a couple of thrifted vintage travel posters, a few minimalist digital prints from artists I follow, and a framed botanical watercolor that belonged to my grandma.
Recently, I decided to refresh my walls and, since handmade reproductions were a bit out of my budget, I went for a more affordable option - canvas prints from WikiArt Store. One of my favorites is “The Brook” by Henri Biva - the soft greens and detailed reflections really add depth and calm to the room. I also picked “Silence” by Odilon Redon for my reading corner; its dreamy, symbolic vibe fits perfectly there. In the hallway, I went with “Still Life with Lemons and Oranges” by Luis Meléndez the colors are so vibrant, it instantly brightens the space.
I haven’t ordered any large statement pieces yet, but I’m considering getting a bigger canvas soon. So far, I’ve been pleasantly surprised by the quality the texture, color accuracy, and overall look feel premium, especially for the price. It definitely doesn’t come across as generic decor.
Has anyone else ordered prints or canvases from WikiArt Store? I’d love to hear how they compare to pieces from local galleries or other online shops in terms of color, texture, and overall vibe.

difficult to find out - i believe
