Why aren't there classes like this in Denver?

I subscribe to a number of blogs.  One of them is Whipstich Fabrics a fabric shop in Atlanta which also offers classes.  I discovered it through Motherhood Uncensored's post which mentions Whipstitch and where her daughter took a sewing class.

Whipstich Fabrics sends out a newsletter which includes her upcoming classes.  Here are twoI would love to take:

1 - Sewing Knits without a Serger.  Self-explanatory and only $145 (two sessions) a bargain in my book.

2 - Patternmaking.  Learn to draft a pattern for that outfit you have in your head but can't find a pattern for.  $185 for three sessions PLUS the text (I didn't get a lot of of this book but it could have been because you need someone to explain it.  Read my review here.)

So why aren't there classes like these in Denver?
