paper twine (or twist up some dark paper)
glue (hot glue or PVA will do)
little pliers (any kind)
branches (I bought mine at a local florist for $15 but you could just find some if you have trees in your area!)
Use paper that is 3 x 3 inches to start, I then used paper that was a bit smaller to vary the size of the flowers.
When your making such small origami, use tweezers to hold and fold, especially this fold:
To attach the blossoms onto the blossoms, you could simply use a hot glue gun, or if desperate, sticky tape.
I instead stuck paper fasteners to the backs of the flowers and used pliers to gently squeeze them onto the branches, I can then reposition them pretty easily without breaking the willow branches.
I also hung some origami cranes from the branches using fishing line, you can view my post on a variety of origami cranes here.
To make the blossoms a bit neater I used the glue to stick the folds on the back down, and also instead of cutting and then folding in between the petals, I just cut out where I wanted there to be a gap.
For the little blossom buds, I used the paper twine and glued the buds onto the ends, and then glued them to the branches.
I used big rocks I got from the beach to weigh down the vase that I used, this could also be attached to the wall at a more horizontal angle.
I used 6×6 inch paper in the video tutorial, I would suggest using 3 x 3 inch paper for your tree.
I also remade the pentagon video, I have found this method easier to remember and follow ⬇
