Work with Dave Neary for an Eclipse Che Hoodie design for conference support.

From Dave:
I would like to make some hoodies for EclipseCon EU, and I've been asked to get them into Q2 budget.

The hoodies should be super simple - zip-ups (probably grey) with the
Clipse Che logo on the breast, and a bigger logo, a by-line, and a URL
on the back.

Can you help me out with any design work needed, and the back-and-forth
with the supplier on the prints and layout please?
