Something small for my sister

My little sister studies to become a violin teacher. I'm very proud of her because it takes a lot of talent and courage to choose this uncertain life over a job with regular working hours and paychecks.
Of course she needs teaching material and being a teacher myself I enjoy to supply her with some "nice" things for work. This time I managed to combine it with my new passion for sewing following this great tutorial at bloom. And this is the final product:

Please excuse the wonky seams.
Finally I could not stop myself from trying PicMonkey and played around with contrasts and colours (not to much):

I like the result very much.
