I started out making a couple for Miss 7 and one for Miss 3... but as you can see things got out of hand and I made a heap more. There are three styles of skirt: one is a full circle, one is a tiered skirt. Both are very quick and easy to make. The third style is the stripy one in the second photo. I found a fabulous wide-striped fabric last year just waiting for an opportunity to make one of these pleated skirts. I've box-pleated the stripes in, so it looks like a white skirt with coloured stripes. I love it - I wish I fit into it, but only Miss 7 does.
I can post a tutorial on how to make a full circle skirt here if anyone is interested. Let me know in the comment section if you'd like me to. I use them all the time as they're so pretty on the girls, and lovely to twirl in, plus SUPER quick.
