Of course you can reduce the pattern. It is easiest if the finished sizes of the blocks are easily divisible by whatever number you choose.
If you do a quick search on the net you might even find the block in a smaller size.
The cheapest way is to use regular old 4 squares to the inch grid style paper and then draw in the pattern using the finished size of each block. You really have to think a bit with this. Like Paper Princess says, remember to add the seam allowances.
Another way is to draw out the pattern and then copy with reducing it til you get what you want.
Then what I consider the easiest way is to find a friend with EQ and let them do it for you. Or treat yourself and buy EQ and do it yourself.
