The idea of spats just thrills me.

My permanently out-of-sych fashion preferences lead me to believe that you will embrace this trend in about three years.  I'll just say it now, and you can store it for future use, okay?

For leather or alternative materials:

Leather, Suede, Skins (among others) or Mood or a host of other stores in the district...

For leather needles and appropriate thread: Manhattan Wardrobe supply among many others...

For leather cement: Manhattan Wardrobe Supply, Mood

For pattern paper or oaktag: Steinlauf & Stoller

Chalk for marking: Steinlauf & Stoller

Buttons: Buttonology, M&J or Pacific Trim

For covered buttons: (*clears throat and whispers... inaudibly)

For alternative closures, if you wanna get fancy: Star Snaps

For decorative flowers (leather and other kinds): Schmalberg Custom Fabric Flowers

Fashion Trims for edging, decorating, or lacing: Daytona

I'll be doing some for myself... Go ahead and hate them if you want... or love them like I do!!!  They're just for me, anyway!
