Now your ready to make some ruffles for the bottom of the bloomers. Take one strip and fold it in half, so the seams are inside the ruffle. Line the raw edge of the ruffle up with the raw end of the shorts (you don't need to turn the shorts inside out, sew the ruffle to the top and then it will fold down when you are done so the raw edge is on the inside). Start one inch from the end of the strip and start bunching and sewing. Just make sure you are only bunching the ruffle, and not the shorts underneath.
When you are about on inch from where you started sewing, stop. Pull the shorts away from the machine and cut off any extra fabric, leaving one inch loose on this end as well, so like the picture you now have unsewn fabric on both the start and end of the ruffle and a small space left to sew it to the shorts. unfold those two loose ends and place the wrong sides together. This will feel a little akward, but it's pretty quick when you get the hang of it.
Sew the wrongs sides of the ruffle ends together and fold them back in line with the rest of the ruffle.
Once you have folded it back line the raw edge of the ruffle up with the raw edge of the shorts and bunch it together to fit in the space you have left, to finish it off. Repeat all these steps on the other leg openining.
Voila! Easy Peasy (as my kindergartener would say) bloomers. Here are the ones I have made this way. It takes no time at all and you can make them in all different lengths to fit what you need!
So go out and enjoy the spring air and the playgrounds, because now you're covered ;).
