PI Day, 2017, late...
I've been experimenting a lot recently with digital designs for use on Print On Demand services like ArtsAdd.com and RedBubble.com. Creating an appropriate digital design in a .jpg or .png file for uploading is, of course, the challenge. There are several ways you might do this.
For all of my digital image creation and enhancement projects, I have been using PhotoShop. Adobe has made this a subscription service so I began using PS because of its reputation and its affordability as a month-by-month service. (I could never afford to purchase the software outright.)
Then a professional designer and Facebook friend of mine turned me on to Paint.Net. Now, the first thing I have to say is, Paint.Net is NOT NOT NOT the website you want. That web site has nothing to do with the software Paint.Net.
Paint.Net is a free downloadable software product that shares the ease of use of MicroSoft Paint with some of the more advanced features of PhotoShop, including layers. And yes, it is FREE. The author asks for a donation but does not require it ever.
You can download from GetPaint.net. Try it.
NOTE (17March2017): Sometimes my mind and my hands don't work too well together. For whatever reason, in the original version of this, I named the product PRINT.NET. Who knows why? I don't. Anyway, the correct name is PAINT.NET. I think I've corrected it everywhere...
Deborah K Smith, PhD
As a self-proclaimed mixed media artist and creative professional, I am in my 3rd career, having spent 15 years as a software developer and another 15 as a university professor. My first love and my most demanding one has always been creating whether it be a drawing, a bit of crocheted lace, a cloth doll, a piece of software, a PhD dissertation, or a piece of digital art. I simply LOVE to make things and I see make and make-over opportunities everywhere. My only regret is that there is no possible way that I can live long enough to make all of the things I see in my mind.
