I did plenty of research on where to purchase the crystals. I finally decided to order from Love to Crystal because it came very highly recommended by other brides who have crystallized their shoes. The prices are unbelievable. I hope that does not mean that the product is lacking - I've never heard it is though, so fingers crossed!!
I used the size chart to help me determine what sizes I should buy.
These sizes on your screen are in no way the "true" size, but you get the idea. The ss5 (farthest left) is actually about the size of a pinhead in "true" size. I knew I wanted nothing over ss16 (which is a tad smaller than the picture) because I've researched that the smaller the crystals, the better the sparkle factor. I know it will be a PITA for me to deal with, but whatever! This is what I want!!
I also invested in some very specific tools. I looked at local stores for these (so I could use coupons) but no one carried them.
Magical Pick - a wax covered, pointy tool to help pick up the rhinestones.
