I had quite a bit of fun filling a chosen document size with repeating patterns using the repeat tool in illustrator on the iPad. I can now see how I could use this for print on demand sites that are not set up for the repeat tile swatch. I have not used society 6 yet, but thank you for the size list link. I had tried Zazzle and RedBubble and had been frustrated with getting my documents ready for upload due to not having photoshop for that stage of the process.

this also provided extra freedom to experiment  how things looked, which was fun. 
Thanks for the class, it cleared a few things up that I had been confused about.
