I wanted to make a simple hammock for my cat, so here is my design

Step 1: Materials

Materials:
A 24x14 piece of fabric (must be thin enough to fit through coat hanger)
2 plastic coat hangers
1 shower curtain rod

Tools:
Sewing Machine

Step 2: Assembly

1. Lay the fabric flat on the ground
2. Lay both coat hangers on either side of the sheet, leaving about 3-4 inches of room to loop the fabric over the hangers so you can sew.

Step 3: Sewing

Sew the top part that you looped through to the bottom part so it looks like the pictures.
This is the body of the hammock

Step 4: Find Somewhere to Hang It

Hang the shower curtain rod between any two upright surfaces and place the coat hangers on the shower rod. You can hang your cat hammock in tons of places. Under a bench, in a stairway, etc. Make sure your cat can get to it easily. I hung it under a piano bench, and that worked really well for me because I could use two beams under the bench to keep the coat hangers far enough apart to avoid it folding up on the cat (see picture). Be creative and have fun
