I wouldn't be without my EQ5. i use it all the time. I can spend hours playing with all the possibilities. I could never come up with all the patterns I have discovered on my own.
I love to create a block and then add that block into a quilt layout. Then I turn the quilt block to see what designs will appear. It is kind of like a kaleidoscope. You never know how it will look when the blocks are turned.
I play with color alot too. If you saw my first ebook Playing with Boston Blocks all my patterns in that book were created on my EQ. I love to discover what if answers. What if I turn this this way. What if I change this color to dark and this color to light. I can see patterns in the combined quilt blocks that wouldn't have occurred to me if I had made blocks and laid them out on a table. I love love love my EQ5 and I think it is so easy to use. If I have questions I just call the customer service number and someone helps answer my questions.
I highly recommend it! I wouldn't want to be without it now.
