[Lab] Lab Digest, Vol 39, Issue 29

Tue May 28 13:47:32 EDT 2013

Hi,

Have you looked at the Cricut?  http://www.cricut.com/home/

This is a hobby machine that cuts stencils and I believe has a large format version as well.  I also saw a machine in a hobby shop in the US that was for fabric stencil creation for screen printing.  Can't remember what it was called, sorry.

John
