Every household has plenty of tp tubes. They make great seedling pots, so why not reuse some of them instead of recycling them. :)
I saw this on Facebook and I wanted to make my own with a little flair. You put in only one seed per planter.
First you take a toilet paper roll and cut it into three even pieces. Then you make four to six cuts with scissors on the bottom of the toilet paper roll, about an inch long. You then fold them over one another.
You can use a little bit of masking tape to hold them if you like. Other tape is not really biodegradable.
You then fill the little sprouting cups with damp potting soil and put one seed in them. Then you put them into a sunny window, and keep the soil damp.
When they germinate, you can then plant the whole thing in the ground.
I put the clothespin decor on mine because I thought it was adorable.

Kimberly Clark is developing tubeless toilet paper, which means the other toilet paper makers will probably follow suit. So if you craft with the tubes, you might want to stock up now.

What should I do with all the empty toilet paper rolls that I have saved? I hate to just throw them away.

I have seen where they make a great wall decoration and it is so simple a child can do it and it looks very nice. Cut the tube into thinner rings, color them with a magic marker or crayons, and then glue them together forming a daisy like or flower design and use a piece of cord or wire to form the stem and more tubes for the leaves. Hang it on the wall and you have a great and unusual design on your wall. You can get very creative with this. I am thinking to have daisies lined on the base boards and up the wall would be an outstanding look with maybe a headboard out of a white picket fence piece. You could also do a display of a large sunflower with yellow paint and brown center. I am thinking of putting this on my kitchen wall.
