Blockbase will run without EQ.
it's both a stand-alone program and an add-in for EQ.
when used as a stand-alone, you can do a number of things with the blocks.
(see the details here:
http://electricquilt.com/online-shop.../#tab-Features )
you can't make changes to the block designs.
you can only preview a quilt layout made entirely of one block.
so BB isn't useful if you want to design a whole quilt layout using anything other than one block.
i don't remember whether or not you can fiddle with the colors/fabrics using only BB.
BB by itself is worth every penny unless you want to design your own blocks and/or quilts.
if it fits into your budget, EQ and BB together are even better.
