Someone asked me to do a project for her making these curtains and over the weekend I started on them. Well, I've had them for about 2 months over the holidays and forgot completely what the lady asked me to do but not until after she reminded me. I told her I had one done, which was honest about that but hadn't cut the amount she wanted and my machine caused some unwanted gathering. Now I'm frustrated and don't know what to tell her. I'm disappointed in myself and want to hide like I usually do. I should have never taken this on and I don't want her to hate me. On top of all of this when I realized I'd made a mess of that I spun out of control with my gf but I'm just now realizing what happened days later. I can't believe I would do this but at the same time it's so typical of me. Anyone else have anything happen kind of like this?

Please help
