I love using sequins. So, it's no wonder I like to hoard them. Hahaha.
A Muse Studio carries fabulous sequins in various colors. The Holiday Catalog is filled with new sequins including shaped sequins. You can check them out here:
This is how I am storing the sequins.
I used the 24 Box Storage System from Harbor Freights.
There are 24 small boxes that fit into a larger box in 2 layers.
A bag of sequins fits perfectly into one of the small boxes. I used my trusty label maker to identify the colors.
At $4.99 per box, I picked up a few of them to store other embellishments. If you sign up for their mailers or subscribe via email, they send out notices on sales and 20% off coupons.
