I had some the silky leopard fabric in my sewing room. My niece Ashton is spending the summer with us. She came into my sewing room and commented that she wanted a pillowcase out of the fabric. Lucky for her, I bought plenty. I actually bought it to make a little pajama set for her little sister.
I can't say this was fun. It went together quick. But your probably shouldn't use stretchy, silky fabric for a pillowcase. If you're up for the challenge, just make sure you have plenty of pins to keep it stable.
The font I used is one of my favorites. It's Harrington from 8 Claws and a Paw.
