Thank You Gifts -- Heart Sewing Kit

I've been trying to find a great thank you gift for my customers. I wanted something flat since most of my items can go in small boxes or envelopes. I've decided on these cute little sewing kits. I just make 2 hearts from craft felt and add some thread, needle, safety pins, and straight pins. They may not all look the same and may go through some iterations but each customer will get one.
