save the date candidate

From day one I pictured designing my own paper goods for my wedding, especially, for whatever reason, save the dates. I've played around with several versions on my computer but haven't attempted the printing process yet. I am beginning to feel a little computer un-savvy as I don't know which programs to use for design/editing/etc... Digital design has been a little overwhelming! 

So, I went with what I knew and came up with something completely from scratch, no computer involved.

It's a rough version as my text isn't exactly how I'd like it and it's a little crooked. And the lighting was terrible when I was taking the picture (with my iPhone). Overall, I was pleased with the result and motivated to come up with a few more! I've got a few things school-wise on my to do list above making save the dates, unfortunately, but I hope to have a little time this weekend. 

Here's a preview of one of the many I've designed digitally... It looks blurry/distorted but I have no idea how to fix it. And I am not loving the shade of green... BUT I cannot get the others to import...
UGH. Again, very computer un-savvy. 

Any suggestions about design programs for Mac?? Or DIY invites/STDs? I love the idea of the handmade mason jar invite but I would like to use computer text as opposed to my handwriting... Heck if I could figure out how to do it, though!

*Side note: I realize you can't see the image above but I have NO CLUE how to fix it. UGH. I promise, tomorrow's post will not laced with such frustration.
