The way I do it does involve some serious math, so you may want to do the math 5 or 6 times like me, unless you are really good at math....I digress.
I got my card trick pattern from www.quilterscache.com. Now, she only shows how to make one block, but she shows what the quilt will look like when you make multiple blocks.
Under her section of quilting lessons, she has a good tutorial about multipling blocks and sizes. Then figuring out how many of what size strips you need for that many blocks, and how many pieces you can get from each strip. It's a good method to learn because you can then create quilts from one block using this multiplication.
EQ is still too expensive for me to rationalize the expense. Luckily enough, I have some friends who have it so if I run into problems with my math, they can plug it in real fast.
It's like a log cabin or pieced borders, it's more a technique you learn that will apply for many things than it is just learning to make the block.
