Today I got an email from Marlene. She is working on a prom dress and has this question: Hi. I want hem a prom dress that the outer layer is chiffon..very delicate..what is the best method and what size need..etc I have hemmed then before but the hems are puckered..what is your methond for hemming the outer layer.
This blog post will show you the technique I use to do a narrow hem. It shows a dress made of satin, but I use the same method for all fabrics. It is not a true web page, but I think you can get the idea from the pictures and text.
As for working with chiffon, it is sometimes a challenge. The good thing here is that the stitching is quite close to the edge, so that minimizes the rippling. I use a smaller needle, maybe a size 9. It pierces the fabric with a smaller hole so it doesn't create snags. The needle will go between the threads, instead of trying to break them.
Also, make the lining (inside) layer a good 1"-2" shorter than the chiffon. I pin the chiffon on the client at 1"-1¼" from the floor. I pin the lining 2"-2½" from the floor. Those dresses are usually so full that the wavy nature of the hem makes it a bit uneven. If you don't give yourself enough distance between the layers, then you get the problem described in this post and shown above.
