Why do I agree to do such things... ughhh

So, I agreed to help someone make a ballet costume.  "Oh sure!" I say.  "It shouldn't be that difficult."

A few hours into it, and I am cursing, and making my husband promise to remind me never to agree to such projects ever again.  These kinds of projects ALWAYS take longer than I or anyone else anticipates. 

... so... 15 hours into this "project" and I am still hours away from being finished.  

I'll post a picture of the finished project.... hopefully soon... this torture will end.
