For five bucks you can get one of those little blue "telescopes" that when you look through it it multiplies the block you are looking at an you can see what a whole quilt would look like before making the whole thing. I invested in one of these years ago and use it all the time. JoAnns' sells them or you can find them on line.

If you scan down to the second item, that is the viewer. This is only one source, the first one I came across.
You can also get one of those little folding two panel mirrors that will increase the view. Another useful tool that only costs a few bucks.
Spending a little on this in the beginning will tell you right away it it is going to work as a full quilt. Good luck
