sewing in the ends. A lot.
I have the first poncho sewn together, and am sewing in all the end strings. Then it's onto sewing Abbie's poncho together and those ends in. Then the fur fur. I will have them finished tomorrow, hooray! (About time too.)
One lesson I've learned, if your strips end up wider on one end than the other your poncho will be slighty off. Hopefully this will not be that noticeable when worn. Hope for me. And my children. ;)
