lue - the connection to the Powwow is more timing than anything else. I've wanted to make a quilt using the design of the windows for some time, and it just worked out that I got it done in time for the Powwow. I did make it planning it would be donated to the school to use as they saw fit, so when it was half way done I showed them and they said they'd love to have it to sell at the Powwow, I made sure to get it done.
The actual event is called American Indian Days - and there are a lot of other activities going on around campus on Friday and Saturday for visitors to attend (all Native American themed) including in depth tours of the campus which includes the Chapel that has the actual windows. The Powwow is the highlight of the gathering, held on Saturday.
