I have 3 bridesmaids dresses that require hemming; no other alterations needed. All are two layers with the outer being Chiffon. I know it will cost almost as much as the dress to have them hemmed. I like to think of myself as a pretty good seamstress but the chiffon is scaring me. Do any of you have experience with sewing/hemming chiffon fabric? Any tips? The fine, thin chiffon hem is daunting. I will most likely get them professionally hemmed. Maybe I will buy some chiffon and experiment. Then I can have another job if all goes well. :-;
