Close-up of the bow on the ruby slippers
This particular bow was deliberately aged and made rough to match the bows as they appear on the original ruby slippers today.
If you look carefully, you can see a piece of fabric between the jewels and leather bow.
All the jewels, although very tiny, are sewn onto this piece of georgette fabric overlay. Once completed, this georgette fabric overlay is then sewn onto a thin leather bow on the bottom.
You can see bits of red threads along the edges of the bow. There's no glue used on any part of the bows, everything involves sewing and this is the same technique that MGM used to make the bows on the original ruby slippers.
