Welcome to GDS!
I started digi scrapping about a year ago when I received a couple of tubs of old photographs. I didn't want to harm the photos, but I wanted to do something creative with them. As the profile on my blog says about digi, "The flexibility draws me ... the elimination of cleaning up glitter, tiny scraps of paper, and glue afterwards ... keeps me!"
I, too, love the flexibility of resizing, recoloring, etc ... AND, I find that I often scrap a photo more than once. Digi is less expensive in that you can use a paper or element over and over again ... plus, if you make a mistake, you can un-do!
I hope you find that you love it, too! Hope to see you posting projects in the gallery and participating in challenges ... the challenges are the best way to learn.
