My niece, Greta, dressed up as Taylor Swift for Halloween this year so I helped make her a glitter guitar just like this one.
I cut it out of cardboard, painted it and she came over and helped glue the sequins on. I considered glitter but decided her mom wouldn't be too happy with glitter ALL OVER everything. We added some strings and a ribbon and she was set. So I didn't measure and my circle in the middle wasn't quite centered but she didn't care. I mean, come on, she's five!
Here she is with her glitter guitar and her Taylor wig. She made a great Taylor Swift!
