Santa Fe is very artsy-as others have said - and very charming. Since you are there for the period of time you are, I certainly recommend ABQ as well. Old City is wonderful. Last time I was there (5-7 yrs ago) there were several quilt shops with awesomely unusual (to me) fabrics and very high quality. Don't have all the names at this point but do a google search and you will not be disappointed.
The Sandia Peak area is great! I've only been in the fall so I would think Spring would be awesome. Enjoy your trip!
