Congratulations on your finished top. I bet that felt good. I think if you could post a picture, we could give more input. Questions I have: How big are the blocks? how busy are the fabrics? Is there sashing? What kind of border do you have?
If the fabric is busy and/or you have a lot of different colors. it may be a good idea to have an overall edge to edge design. If there is sashing, it may be nice to have a rope or something like that in the sashing to set off the blocks and then have a design inside the blocks. Lots of options.
