Now that June is upon us, it’s beginning to really feel like summer.

This DIY Hanging Diamond Decor tutorial is a great way to offset that summer heat. Don’t they remind you of ice cubes floating mid-air?

Plus, with all the diamond-shaped products out there these days wouldn’t it be a blast to throw an icy cool diamond party this summer?

I hope you won’t forget to send Sugar & Cloth an invitation!

These DIY metallic diamond mobiles are fun to hang as an overhead table centerpiece or for photo backdrops, but you could easily leave off the string for modern tabletop décor.

How To Make A Hanging DIY Diamond Decor

Step 1 - Materials DIY Hanging Diamond Decor - Sugar & Cloth - Home Decor DIY - Houston Blogger Ashley Rose #diamond #diamonddecor #diydecor #tutorial #diy #hanging #homedecor

Step 1 — Prep your straws.

Cut your straws to the desired lengths. The step-by-step photos for this tutorial show the largest of the three diamonds pictured. The lengths of the straws used are: six — 7 1/2″ straws (long), six — 5 3/4″ straws (medium), twelve — 3 3/4″ straws (short).

If you want to replicate the other diamonds in the photo, the medium five-sided diamond used: five — 6 1/4″ straws, five — 5 1/2″ straws, ten — 3 1/2″ straws.

And the smallest five-sided diamond used: five — 4 1/2″ straws, five — 3 1/4″ straws, five — 2 1/2″ straws, five — 1 3/4″ straws. You can always play around with straw lengths and make whatever size best suits your space.

Step 2 — Cut your muffler tape.

Cut pieces of muffler tape in corresponding lengths to the straws. Because the tape is so wide, cut each piece length-wise; therefore one 6″ piece of muffler tape will cover two 6″ straws. 

It isn’t a bad idea to cut the tape a tiny bit longer than your straws – you can trim the excess later.

To cover the straws, the best way to ensure a wrinkle-free covering is to carefully peel off the tape backing, lay the tape flat on your work surface, place the straw along one edge of the tape, and then roll forward smoothing the tape as you go.

If you have excess tape extending past the end of the straw, trim it off.

Step 3 — Connect your straws.

Time to connect the straws! Tape the end of your string close to the pointy end of your wooden skewer – this will be used as a needle to make threading the straws easier. Slide two long and one medium straw onto the string.

Pull the string taut so that the straws form a triangle and tie a double knot where the two straws meet. Cut off excess thread.

Step 4 — Rethread your straws.

“Rethread” your needle if necessary. To create the next five sides, simply slide the needle through one of the long straws on the existing triangle (leaving a few inches of thread to tie off with) and add another long and medium straw; tie off as before.

Repeat, rethreading as needed. For the sixth side, slide the skewer through the two long straws and add the final medium straw; tie off. You should now have a six-sided pyramid.

Step 5 — Construct your upper trapezoidal facets.

To add the upper trapezoidal facets, slide the needle through one of the medium straws on the pyramid and add three short straws.

Pull tight and tie off. Slide the skewer through the next medium straw, the adjacent short straw, and add two short straws; tie off.

Continue to add facets in this way, two short straws at a time, tying off after each new facet. For the last facet, slide through the short, medium, and short straws, and then add the final short straw. Tie off.

Step 6 — Hiding your knots.

To tidy up the diamonds, use the skewer to push any knots visible at the intersections into the length of the straw.

How To Hang Your Mobile

If you want to use the diamonds as tabletop decor, then you’re done!

If you would prefer to hang them, use string (silver cord is pictured, but you can use clear thread or whatever you like) and tie 6″ pieces to the exposed strings at the top intersections of the diamond.

Tie these six strings together, and then tie a long piece of string onto this knot. Tape the string to your ceiling and trim any excess string.

If hung in direct sunlight the diamonds reflect onto nearby walls, disco ball style.

In lower light, they can make gorgeous shadows if hung near a wall!

  5. I just did this diy. I gotta say it was definitely a pain in the ass and I may have carpal tunnel syndrome from it, but it was worth it. I only made the first diamond, but I already hung it up and even by itself it looks amazing. It added so much personality into my bedroom!

  6. I got to the last step and I’m lost! When you say, “For the last facet, slide through the short, medium, and short straws, and then add the final short straw.” I’m not sure which short straw i’m supposed to be sliding through for straw #1. the adjacent straw? how many facets should there be on the top of the triangle, 5? ahh!

  7. love at first sight. i’m trying to do it right now. and it’ s IMPOSSIBLE!!! i have my 8month old daughter helping and she loves to mess up the strings and straws..sigh ….
    will continue later …. thanks for sharing!

  8. Very cool looking! I wonder if you’ve ever seen (and thus been inspired by) finnish christmas decorations called himmeli? Same principal in the making :)

  9. I did this project last night… I didn’t want to hang the diamond, just use as a table or bookshelf piece … I hadn’t thought it through and since the instructions say you can do this .. I assumed it would work.. Wrong. If you’re not going to hang these you will need to use something with more structure than string. I had an epiphany this morning and realized I had some unused silver pipe cleaner … I pushed small pieces of that through each of the top “corners” until it had enough structure to stay in shape on it’s own.. I think any kind of thin flexible wire would work, just so happened that I had pipe cleaner lying around and I didn’t want to spend any more money on this project .. Anyway, it turned out great! Just a heads up for anyone in the future :)

  10. Quick material sub- what you want is aluminum foil tape in the heating duct section. Muffler tape has asbestos and is pricey.

  11. I linked this post on my site:
    I hope you don’t mind it (: <3

  12. Thank you for this post. What a great idea!

    Found you from Oh Happy Day, and these were perfect for my Father’s Day table decorations.

    I had a little trouble getting the cotton string to behave as desired and ended up abandoning the process for hot glue. This worked well and was a fast alternative. I ended up hanging the diamonds with thin silver wire, which gave the tops of the diamonds nice structure. This may have also been a good substitute to cotton thread.

    After I finished, I realized spray pain could be a fun alternative in lieu of the silver tape, should you want to try another color scheme apart from what is available in tape/straw colors. Maybe for next time :)

    Had a fun time and thanks again. Great tutorial!

  13. I was shocked to realize this was made out of straws! Looks like it takes some time to cover them, but wow what a result.

  14. love that the metallic tape makes these look all grown up. I’ve seen this done with neon straws which gave the shapes a completely different feel. A bit more whimsical
