Like I've mentioned a million times before, we were in such a hurry to get everything done. In an attempt to make this project go a little faster (tufting isn't all that hard... but it can be time consuming), I realized that I could completely bypass the whole threading-a-button-through-the-headboard-holes thing by just carefully screwing a wide-headed screw down in through the hole I had made in the foam.
It's important to use screws that aren't too long (unless you wont see the back at all) and that have a wide enough head to hold back all the fabric from the tuft. I used a little bit of high-loft batting and linen in the same magenta color to back the headboard and cover any of the screw holes.
This little trick saved me literally hours of labor time! And it looks great! I just used fabritac to glue in the buttons into the tufts and I think now it would be hard for even me to tell which headboard was the one I spent more time on! :)
Oh! I also wanted to mention another little tufting trick I discovered a week or two ago. My sister, Ali, is about to have a sweet baby girl (yay!!) and she wanted to redo her bedroom before the baby came. We made a tufted headboard and the velvet we were using was a little thick and it was getting tricky to make the fabric not look too lumpy. I cut deep grooves into the foam and that made a little pocket for the fabric to sit into AND it made it super, super easy to get the diamond shape perfect and nearly wrinkle-free every single time.
