My "duh" moment was when I had completed a handbag for myself and gave myself a big pat on the back for a job well done. I grabbed my old handbag and started putting my things into my new bag which kept making a crinkling sound every time I put my hand in it. I finally figured it out......I was out of stiff interfacing to use in the pockets so used Steam A Seam which worked well, but I forgot to take the paper backing off!! That took the wind out of my sails real quick!
