The Leonardo petal pullers are a custom tool I developed that will make creating flowers and petals very easy. It has a tweezer length of 8 inches long. The small, medium and large pullers allow you to pull petals approximately 4mm by 17mm by 25mm to 4mm by 20mm by 30mm, possibly larger. The size of the petals depends on the amount of glass pulled or pressed. The tool has many uses, just use your imagination. Basic Instructions will be sent with purchase of puller. If you are still unsure how to work the tool I also have a DVD available. Look for classes in your area.
