I tend to work on several projects at the same time...mediums need time to dry [too lazy to get out the heat gun *winks*], sometimes I can't decide on which creative direction I want to head to OR I'm just having a bad art day [Believe me, it happens a lot...*LOL*]. So when it's a good art day, batch processing is the way to go for me.
Like with this card. Since I had the sewing machine all set up for my layout stitching, I put together some paper scraps for a quick card too. :)
What about you? Do you need to work on a project from start-to-finish before you move on? OR do you want on several at the same time and batch process them if they include similar materials/techniques?
