Learned a Hemming Techinque

In my excitement to add elastic to an ankle hem, I sewed the elastic into a circle before hemming the loop it will go inside which I also have yet to hem. That is horribly expressed, but basically, I should have hemmed the fabric first, leaving a portion open. I would then thread the elastic through the hem loop and close the circle. I can still complete the hem the way I have things now; I just could have saved myself a lot of trouble.
