Last minute Olaf DIY for adults If what you want is a last-minute Disney Costume idea, the only thing you need to do is use your favorite T-shirt Sewing Pattern and sew 3 black circles of any scrap fabric to it to form the buttons. As for the head, you can get a White Cap, make a cone out of Orange Fabric Scraps and some Poly-fil Fiber for the nose, glue 3 Pipe Cleaners to the top of the cap, and draw the eyes with 3D Black Fabric Paint.
