As you will see below, in the end, I went on and wrapped up the project and pitures without the bedskirt, but I plan to add a bedskirt that starts at the top of the box spring and drops to the floor. So in the end The actual pallet platform will be pretty much covered by a straight pleated tan colored bedskirt to tie it all together. This is a project I will go to Hobby Lobby for and then sew to my needed dimensions. :)
This just made it easier for me because I could just start upholstering and did not need to worry about cutting boards etc. I purchased foam sheet (pictures below with dimensions) from Hobby Lobby along with my fabric. Used 40% off coupon and fabric was $47.00
Foam was $11 total for all boards.
When cutting my fabric I allowed 6" of length beyond the 25x25 measurement so that I had no issues getting a sufficient amount of fabric to staple to my board. I was scared of that and I definitely didn't want to shred my fabric on the back of the board for it to just loosen and come off after all of this work.
I folded my ends under and stapled into that to give more support for the fabric under the staples.
Took me a few hours to upholster all three boards and then it was done!!!
I purchased hardware to attach my upholstered boards to my wall and screws with anchors in case I had to mount them to the wall in between studs in some places. I really wanted these sturdy and not a risk of falling or slipping. I wanted them mounted securely. The hardware total was about $6.00. Total cost of new headboard $82.00!!!! I'm very happy with this project. Super thrilled to have the bedroom redone and at such a great price! Also, this was my first upholstery project so it's not a gorgeous picture of the back of the upholstered headboard pieces, but it's not that bad for a first time either! I'm so excited and now I am trying to figure out more projects with upholstery to do around the house!!! Hope this is helpful and inspires you to remake a space in your home as well. :D
