Muslins are brilliant.
They give one an opportunity to get familiar with a pattern before attempting it with a nicer fabric. Also, they help with fitting. I'll spare you the pictures of me wearing the muslin. I seriously have to take in the shoulders and add an inch to the waist!
Hopefully today I can get some dress lining and begin to cut out the real deal. First I have to wash my fabric, fold mountains of other laundry, make cinnamon rolls, and make dinner for the missionaries! So we'll see.
