I learned about making grown-up decor from tp rolls some time back with an Activity Days craft where we made "Forget-Me-Not" wreaths to go with President Uchtdorf's memorable talk from LDS General Relief Society Meeting in 2011.
You can find tutorials all over the internet about making wreaths and wall art from tp rolls - like this cute summer wreath, this lovely wall art, and this faux metal art (even Hungarians are doing it!).
I had actually been trying to find something to make a napkin holder from. We have bought paper napkins over the year and they are just taking up cabinet space as we usually use a big roll of paper towels. I realized this tp roll technique might be just what I was looking for!
I'm not going to do a full-blown tutorial, there are so many out there. I will say though that hot glue is a million times preferable in my book to any of the glue I saw ladies out there using since it dries immediately.
I joined four flowers together for each side of my napkin holder and just made two lines of tp roll petals for the base. I used a generous amount of hot glue to attach the sides to the bottom so it would be sturdy.
After polling family and friends I decided it would be cuter au natural and I just had Chiquita help me cover it with modge podge to seal it. It was hard to have her help too much since the layer of modge podge needed to be thin and the painting was delicate, but she loves to help and I love to have her involved.
It turned out really nice looking and has held up very well (I made it in September).
