I have EQ5. I certainly don't use it to it's full potential but it can be very handy. I'm not overly creative. I usually use it for putting together blocks then see if I like the border proportions; different colorways, etc. It will give you yardage requirements but it's not the most effecient use of fabric. I will say, I've not come up short any time I've used their requirements for any projects. Just a small word of caution...I recently got a new computer which operates on Windows 7. It takes EQ5 a bit longer to load and the graphics aren't quite as sharp. It does function fully but if you see a computer upgrade in your future you might want a later version of EQ so they play together a little better.
