If you waited until today to start working on Halloween costumes, you’re in luck! There are some great resources out there with inspiration and instruction for easy costumes.
Disney Family Fun has a huge list of costumes and accessories with easy to follow instructions for many of the ideas.
Martha Stewart has over 50 Halloween Costumes and instructions (some are more time intensive than others).
And for more ideas, a search on Google image search or Pinterest brings up tutorials for individual costumes on many craft and sewing blogs.
Have a safe and happy Halloween!
