You're now ready to download and open the Ponoko starter kit for Inkscape
Once you've downloaded the starter kit, you'll see there are 3 Ponoko templates to choose from.
Open the P1.svg Ponoko template. (You can double click on the file or use the menu options inside Inkscape (File > Open) and then find the file P1.svg from there.)
You'll see an orange box with the words 'safe area' when you open the P1.svg. For these decorations you'll be working work with the smallest material size available - the P1. Its dimensions are 7.1 x 7.1 inches or 181 x 181 mm.
If you're interested, you'll find the starter kit includes the Ponoko making guide which contains all sorts of helpful information about designing and making with Ponoko.
