I bought cheap headbands at the dollar store.
I had felt on hand, you could use foam too.
Cut a crown shape on the folded edge of a piece of felt.
Glue the center on the headband.
Fold up and glue together. Causes some wrinkles, but no biggy.
Next, decorate with plastic rhinestones.
also available at the dollar store...
For the Princess Birthday party,
I held the glue gun and glued the stones
where the girls wanted them.
It took some time to get all 8 girls crowns done,
but I didn't want any of them to burn their fingers.
These crowns are so fun.
I glued them on slightly to the side
for a whimsical look.
