Make your own shark anatomy model with supplies that cost only a few dollars.
This 23-page PDF includes step-by-step instructions, a descriptive materials list and 9 pages of pattern outlines.
The materials you will need to make the shark are felt, plastic packaging like a milk jug and a 2 liter bottle. You could make it entirely by hand but it goes much faster with a sewing machine.
The PDF will be emailed to you as a digital file within 24 hours of payment so you don't have to wait to get started!
