I used denim and drill cloth and a green striped cotton for the piping. My kids drew all the bug pictures which are embroidered on the curtains and pillows.
Here is the caterpillar pillow. Rose originally drew it as a woolly bear. Orange and black were not in the color scheme, so, with Rose's blessing, he became a yellow and blue caterpillar. I love his happy little face. He just looks so friendly and caterpillar-y to me.
