One trick is to cut out of paper (even paper bags, etc. something cheap) a pattern of the pictures. Hang those with tape and then when you get everything where you want it - you can go from there to hang your pictures. I know I have seen tips on several blogs for hanging pix like this, but I can't think of what blog(s) right now! Maybe google?

Yes, I thought I had seen it too, but when I did search, all I could find were tips for more randomly arranged gallery walls.

Four years ago lolauren posted her approach to hanging an art grid in her DR and the lovely results. I searched for her post but couldn't find it. IIRC it was as tinam61 suggested. However, I'm not sure whether the arrangement was as linear as your inspiration picture. I do know I followed whatever lolauren posted and was able to get good results. I used Command strips; no nails.

I think it takes a specialize brain for that! I couldn't do it to save my light but DH can do it blind folded (not really) But, he measures and figures out patterns/layouts for a living. Another thing I've learned from him (wouldn't work for this situation tho) is to not always get caught up in precise measurements and centering, etc. Let your eye tell you what looks good. Good luck!

I have only hung a grid of 4 and did indeed pull my hair out with all the measuring, remeasuring and stress. And a laser level.

If you are hanging 9, for example, I would start with one in the middle and work out from there I think, after you decide how far apart they will need to be. If they have been custom framed with wire hangers, the wires are not always exactly the same hanging distance from the top which makes it harder IMO to get it right.

I wouldn't attempt that but I also don't attempt to hang even two pictures side by side. I just don't go there.

I've hung grids before (even 24 and more) and it depends upon how consistently placed the frame hardware is on the frame. Use a level and hang one row at a time. I find the closer they're hung, the easier it is to get it right. Tiny distances in between frames are more forgiving than larger gaps, believe it or not. Mainly because the end result looks more cohesive as a single unit.

That's good news, because I do want to hang them close together!

Here's a foolproof method:

We did this at our beachhouse. I'd guess we have 18 or 20? The most important thing is to start with hardware that is precisely, uniformly placed. Are the items already framed?

Lay them on the floor and then stand on a chair to test optimum layout and spacing. After that it is just math.

Once they are hung, they will drive you crazy because gnomes are well known to shift one or two every night while you sleep. This can be addressed by velcroing two corners.

I use blue mactac on my frame corners and highly recommend.

Didn't read the responses. I take poster board or newspaper and cut to the size of the frames. Attach to walk with painters tape on back. Grab paint stick, drill a few different holes in the center (toward top, middle and bottom) add small, short screw into one of the holes (think I use the middle hole the most but depends on what you're hanging and where). Hang the picture off that screw and place over your taped poster board on wall. Line up and use that screw to make a tiny mark/dent on pb/wall. Put pic down and run your nail into the wall. I use this all the time for hanging and it eliminates mistakes for me. Of course you'd remove your poster board once you're sure pic is in right position.

Note I just move the screw around on the paint stir stick if need be instead of adding a screw to each drilled hole.

Um, I meant to post this on the decorating side. Just realized that. Oh well! I hung the pictures today. It is humid and unseasonably warm here so I literally worked up a sweat doing it, but it's done. I need to get some of the blue sticky stuff to adjust a couple of wonky spots, but I actually think I did okay. Will post pics after I de-wonk the arrangement! Thanks for all the advice. I started with the bottom row of pictures (after doing a lot of math) and worked my way up, and it seemed to work well that way.

Here it is. Now I can obsess about what to put on the console. I just parked that stuff there experimentally. And it looks like I need to move the console to the left a bit...

DH is happy -- these are all his photos.

Hard to get a good pic because of the light...here are a few close ups of my favorites.

They're all nature-y except for this glamour shot of our dog. She's curled up in a faux fur blanket. She's kind of a princess.

Sue, that looks wonderful. What a tribute to your DH's photography skills too.

Well-done! The photos are so interesting and you did a fine job hanging them.

Looks great! I like your choice of what to hang next to what.
