Imagine my disgust when my brother came to visit, bringing all his mending along. Says he, "I know you like to sew, so..." Replacing zippers in his pants was agony!
I have found that Lazy Girl Designs offers some good, easy methods for putting zippers into bags. The "Runaround Bag" has especially easy zipper instructions. Unfortunately, I just can't get the hang of the kind of zipper that uses only one side of the teeth, where you take the pull off and then put it back on again ("Becca Bag").
