Your bows are pretty! Good job! I am with everyone else on sealing the edges. I use a lighter or fraycheck on my bow edges. Also, you can go online to
www.hair-hardware.com and find some tiny alligator and french barrette clips and sew them on the back. I don't know if they ship to Korea but it is worth a try.....ebay is always a great stop too! I have gotten cute ribbon and buttons from there often
Good luck!! Bowmaking is fun!!!
