Q: How do I start designing from a canvas?
A: To start a project from a canvas, on the home page, click “Create New Project”. You will be taken to the design screen. On the left side of the screen, click “Set Canvas”. A new window will open showing the different canvas types. Choose the canvas that is most similar to the project you are going to create. This will help you design and visualize the project prior to cutting.
My Explore should be arriving soon and I'll post some of my own reviews and tutorials. Until then, I'll be crafting with my Expression and CCR!
