Get tons of toilet paper rolls
Fold it in the middle like this
Cut in the center of the roll
Then again so you'll have 2/4 of the roll
And again, so it will have 8 thin rolls
If you want, you can cut again so to have slimmer rolls, but depends on your project
You can glue two parts like this
And make different forms from that
Other idea is to cut the slim roll on the mark
And make little details on each roll
This is what i did, painted gold and framed a mirror
Made a pattern and glued a mirror on the center, but be creative, you can do frames for photos, works of art, you'll find lots of ideas on the internet!
Is not very regular though :p good work upcycling your rolls!
