Too bad you didn't get to Peach Tree.
There is a nice shop in Grovesnor Park Mall, called Periwinkle Quilts. It's a nice little shop, but not as much fabric as Peach Tree. If you are going north on circle drive, and turn left(west) onto 8th street the mall is a few blocks down on the north side.
My favorite fabric land is on Preston Ave too. Turn north off south Circle drive at the Preston Ave exit and the Preston Ave Mall is a few blocks up, on the east side.
I used to live in Saskatoon years ago, but did not go there too much for years. Now both sons live in small towns just south of the city so I have had to learn how to get around again, so much has changed.
Enjoy your visit there, it's a beautiful city.
