Margaret was married to Charles Rennie Mackintosh, a famous and talented Scottish architect, whose career and work probably felt the influence of his equally talented wife.

I love the contrast between the sophisticated fabrics and colors and careful sewing of the background with the roses, edges unfinished, a bit 'rustic.'
I can't wait to take it to her!
Enjoy!
