made from a packed of a thousand mother of pearl ones that i got for $5 or something...but they're a little bland since they're all shades of white. i thought the red perked it up a little bit. the tourquoise ones with the lime green thread are fetching too, don't you think?
Plastic buttons will dye---you can use rit or Tintex. Sometimes the plastic will absorb the dye at different rates and you will get lovely striated or mottled effects. Thrift stores are a good place to buy buttons cheap--they sometimes bag gavillions of them to get rid of them fast and cheap.
Mother of pearl buttons can be dyes also.
I love the idea!
