We got this nest idea from montessori mama's post today and decided to get right to work building our own nests. We just read The Best Nest by P.D. Eastman, so we found materials similar to the ones Mr. and Mrs. Bird used to build their nest:
stocking string (yarn)
hay (paper confetti and basket filler)
horse hair (pink Easter grass)
We started with the rolled-down brown paper bag (I helped with this step), and they painted glue inside their nests and up the sides. Then they went to town adding gobs of nest-building decor! We'll put Easter eggs in when they are dry (they also used gobs of glue!).
This was a fun and easy project!
