I had a dinner engagement last night so I missed posting day 3 of the pigtail challenge. So here is day 3. Start with the 4 ponies as laid out in the challenge. Once again I did 2 small ones at the front and 2 bigger ones at the back. Divide both the little ponies in two. Two smaller sections in the middle. Combine the two smaller section so that you effectively have three strands to braid. Braid back toward the bigger piggies and when you get closer, split in half again and attach into the big piggies with elastics. Fulfills all the requirements - simple, quick but still super cool!
And day 4 I decided to reverse things to shake it up a bit. I stuck with the same config of piggies - two smaller ones at the front and two bigger ones at the back. Rather than adding the little piggies into the bigger ones as is the general way of doing things, do the opposite. So take the bigger piggies, cross them over and then elastic them onto the two smaller piggies at the front. Because of the size difference you will find the the elastics won't overlap but it results in a cool criss cross look. And I love the funky piggies at the front of the head. This would also look fab with messy piggies.
