At least you came out with a really nice quilt! The colors are cheery and I love the way you quilted it.
To summarize what others have said:
When you build a block in EQ, you specify a block size. This size is useful while you're designing the block, but this block can actually be made in any size at all.
When you do a quilt layout, you specify the size of the blocks in the quilt. You can then put any block (no matter what size it was built as) into the blocks of the quilt. The information at the top of the screen tells you the size of the quilt, using the block size that you specified in the quilt's layout. If you print the fabric requirements for the quilt, it will be based on that same block size. You can create a quilt in EQ, then go back in and change the blocksize in the layout. The quilt will still look the same on the screen, but EQ will change the size that is displayed at the top.
