Simplicity Studio Simpli-Ez Piping Wizard
 

I bought this tool at Tuesday Morning Store for $8. I guess it's purpose is to make perfect seam allowance of 1/4" or 1/2" with 1/8", 1/16" 1/4" or 1/2" piping. Not much about it online that I can find. TM store here has the 6 ft long cutting mats for $30.

I found this How to use on Simplicity http://www.simplicity.com/t-Simpli-EZ-tools-tips.aspx

I found that site too but it only list the instructions that are on the package. I guess it's easy to use but I'd like to see a demo.

Darn I didn't check to see what they offered but just written instuction the same as the package I guess in case they were thrown away...lol. You might have to learn how to use it and make the demo for others to see. If you find that the Simplicity Studio Simpli-EZ piping Wizard works great you'll have to let us know one might be a future purchase!
