piano keys borders
I am making a wall-hanging approx. 30 by 50 inches and plan to use a piano keys border on it. For those of you who have made a piano keys border, what size should I cut the keys? I was thinking perhaps cutting them 1 1/2 in and finishing at 1 inch. Would that be too small? or too wide? And how wide should the finished border be? I hate sewing long strips together as I always manage to sew them wonkily (is that a word?). Thanks for any advice yall can give me! also, has anyone tried putting black keys into a piano key border at the proper intervals....just like a keyboard? Thank you for your input.
