I decided that ten years in the closet was silly no matter the sentimentality, so I decided I was going to alter it into a shirt so it might see the light of day. I chose a day when hubby wasn't home since I knew he wouldn't be too happy because he liked the thing. I put it on over the slacks I thought I would wear with it and rolled it up to the length I liked and pinned each side to tell me where the length I liked was.
I then placed it on my dress dummy, the first time I used my present from my mom. (If you want to make your own dress dummy, if your mom doesn't surprise you with your own, see this post.) I used a measuring tape to make sure the pins I stuck in where the same length from the arm pits and then used the tape again around it like a belt which I used as a guide to put pins all the way around the dress where I was to cut it off. My two year old was begging to get the "pretty princess dress" off the dummy so she could wear it, unfortunately with the next step that I am about describe she burst into tears and was no longer happy with Momma's sewing project.
So, I cut off the fabric with scissors about an inch below the pin line. I hesitated for a bit knowing how not-so-great a sewer I am, but decided to be brave. The kiddo was not thrilled with my bravery.
Then while still on the dummy, I flipped the hem under and pinned it to visually see that it was nice and even.
Then I ironed the flipped edge flat. Did the first sewn hem around it, this time going slowly and carefully in the machine instead of the maniacally fast sewing I generally do. Then I cut off all the excess fabric and rolled the hem up and rehemmed again so that the fabric didn't unravel. I have to say I was pretty proud of my first real hemming job, it looks good on the outside AND the inside.
