*Choose fabric you already know probably isn’t appropriate for the project (but look how well it coordinates with the trim!).
*Don’t prewash the fabric.
*Be arrogant enough to think that just because you have made oodles of complicated Victorian era costumes, surely you can easily do one from a ‘less challenging’ era.
*Don’t study the pattern or instructions ahead of time.
*Don’t make a muslin.
If you follow these simple steps, you too can have a costume that will fit terribly, look hideous, and end up in the trash can. Have fun!
