Be sure and try to have time for the Quilt Museum in Golden I think.
I've not been there yet, the one time we were there I was on crutches and they were closed.
My preferences: or at least the places closest to me...
If I am looking for something specific, I can usually find it at one of these three. Also great staff and very helpful when you need an idea or two.
Holly's Quilts -County line and Colorado Blvd.
Since Great American Closed down, they have expanded their store, and have a good assortment of everything.
Creative Needle- South Broadway and Ridge Rd
Marge and her crew have a lot of everything too, and Cross-stitch and machines and parts.
High Prairie - Out in Parker (sorry don't know the exact address.
Jeanie and her staff have just expanded this store too, although I'm not sure that they are as big as the other two.
Up north off of I-25 and 132nd there is Tomorrow's Heirlooms.
This one was bought out 1-1 1/2 years ago. They are not the store they used to be, but they are creating a new place.
I am sure there are a lot more smaller quilt shops that you can google and find.
Although I do know of 2 up north where you will be that closed down in the past 3-5 years due to illness or the economy that would have been nice to visit.
Good luck,
Susan
