Because it was going through the mail, I didn't want to rely on glue to hold the fringe-y trim on, so I found some colored staples in my stash and used those instead.
And I love to use those little paper drink umbrellas in my collages. Just open one up completely (it works better to do this BEFORE enjoying too many of the drinks that accompany said little umbrella), snip the little white spokes that hold the paper to the stick and work the stick through the hole at the top. I just affix with white glue like Elmer's and they end up wonderfully translucent.
And look at the laundering instructions on the wrapper from really old embroidery floss...it recommends using Ivory soap.
