I've only heard good things of them and in fact, am just finishing up a course with them...Sketch Support with Allison Davis and had a great time. Everything went smoothly, I got a ton of pages done and learned a LOT about sketches and how to get the most out of them as well as some great scrapbooking tips. We were given a sketch at the beginning of every week along with a sample page by Allison. She talks about what she did to change the sketch, the thought process, photos placement, embellishment choices, paper choices etc. Each week was a different topic with an assignment and challenge. Once we have finished our assigments, we shared in an online gallery and got feedback from her and everyone else in the class. Sharing and finishing assignments wasn't compulsory. Here's an example from week 4...learning how to embellish.
My interpretation of the sketch...assignment was to create a layout and adjust the title, journaling and/or embellishments to fit what you want to use.
