I have been quilting for 2 years and also wonder if Glacier Star is doable for a newer quilter. It looks very difficult. I have done some of Niemeyer's easier patterns, (Wild Goose Chase). I will watch this thread.
This bargello is the quilt I have made with the most wow factor. It is all straight line stitching and was quite easy. You just have to keep your colors organized and carefully follow the pattern. The pattern is Links by Dereck Lockwood.
I am sure your parents will appreciate any quilt you give them.
