Bonni's Pajama

I did my own version of Adventure Times' Princess Bubblegum's pajama shirt. I did it with this cool free programme called MyPaint. It's a digital painting programme so you can't edit photos with it, but it's relatively light programme (it's only ~30mb on my laptop hp530)
Also I can recommend a programme called Alchemy, if you ever feel stuck on not coming up on ideas. Alchemy is also totally free programme. They have also browser version of it called Webchemy. Alchemy is sorta like skribble programme that creates mess from which you can create art. Mess <3
