The classic costume - make a ghost out of a sheet. The Updated Version: make a cute ghost out of a pillowcase (still in the sheet family). I LOVE this! I saw this at a local craft fair and knew I could whip one up. I think it's so versatile - it could be a costume, or it could just be a festive outfit for everyday wear in October. I think it'll be perfect for my preschooler to wear when she tags along with me helping at school Halloween parties - or to wear to the library Halloween storytime, etc.

Hold the pillowcase up to your model to see how long you want the dress. Remember adding the band at the bottom will make it longer.

Then cut some eyes and a mouth out of the black - so many options with this step - mean face, small mouth surprise face, crazy face, etc etc...
