We made a pink teepee for the girls last weekend.
This is a very simple project. You just need 5 or 6 wooden rods ad a piece of fabric. You can just tie the rods togehter but I recommend, for a better stability, to pierce the rods and thread a piece of string into each hole, then tie it up around the rods.
You can then set up the structure and cover with a piece of fabric (I used two large fabric rectangles and covered with a tulle curtain).
You can easily fix the fabric with clothes pegs.
I just added my personal touch with a belly dance waistband.
The teepee is ready, and it can be used both outside and inside!
