I was at Marshall's Home Goods not to long ago and I saw this cat sack (I don't know what they're really called) that cats can hide inside. It has a price tag of $40, and while it was kinda neat looking and super soft...there was no way I was going to pay that much for something I knew I could make myself.
First you'll cut out 4 pieces (2 of each color), you can make the sack as big as you want as long as all the pieces are the same size.

Next, you'll sew up each bag like a pillow case, sew the 3 sides ... but leave the top open

Once both bags are sewing on the 3 sides, you'll connect the openings. If you're using a patterned fabric, you'll want the wrong side facing out for this step.

With the wrong sides pinned together at the opening, you'll try to sew the edges together being careful not to sew the opening closed. Leave a small opening so you can flip the bag right side out.

Flip the bag and then pin the opening closed and sew it up.

Once it's sewn, find a cat and stick her in the sack


Thanks for looking, C & C welcome.
