I found a free editing program called lightworks. It came with a warning that there is a steep learning curve and they were right!!! Not only do I not fully understand (yet) what I am doing but my ancient laptop (only 3 years old) has a hard time rendering the previews. So this second video was made with a great deal of trial and error and no preview, but I think I am starting to grasp how the program works. Which means the next one will be so much better! (....although I may have to reformat and defrag before I do more editing!)
The tutu painting is still available on Etsy!
