Final Alteration-Sizable Waist!! First Pair D-O-N-E!!!!!!

Woo Hooo!!!!  I made my first alteration for making a sizable waist on Sunday.  You know the elastic waists that are in some of younger children's clothing?  Well, I am  a personal seamstress to a dear friend-and she was wondering if I could make a pair of uniform pants for school into a "sizable" size-so that her younger son would be able to wear them when he gets old enough for school-so I said sure I would give it a go....

All in all I am very excited about it and I think it turned out well-course I will check with her to see if this is what she wants-before I do the other pair : )

UPDATE: She seemed to really like it : )

I am just so excited that these turned out well!!!  Especially with no help from the internet!!  As far as I could find there wasn't a single tutorial on how to make a sizable waist-can you believe it?!!!  So I did it all on my own : )!
Here is a picture of the

Is anyone interested in a tutorial in learning how to make this?  If so please leave me a comment....:)
