I have EQ5 and it is my most used tool. I love it! You can scan your own fabric into the library section and then you can see your quilt with the fabrics you plan to use. It gives me a chance to audition and play around with color combinations. I also like to use the turn the block feature and I get designs I never would have thought of. I probably have 2 or 3 thousand designs on mine. I will never make them all but I love playing with the color and ideas it presents. You can draw your own blocks and that is the best feature for me as I do things a little differant than most and it lets me be creative and if Ihave an idea I can see if it will work without having to cut and sew fabric. I love mine. I have debated on getting the EQ6 but I might wait now til the next one comes out.
I have called the company a couple of times for help and they are very nice and helpful! Highly recommend EQ!! :D
I also use it to record a block or quilt idea that I want to try out. I just go in and recreate the block that I saw so I willl have it to go by.
