* change silhouette settings to leave dxf instead of scale to fit
### Cutting
* blade settingon silhouette was #2
* open the dxf in silhouette and cut the vinyl
* 70 micron vinyl was [ordered](http://www.ebay.co.uk/itm/191422915226) from
[thevinylwarehouse](http://www.ebay.co.uk/usr/thevinylwarehouse) from ebay
