Cross Stitch Quilt Blocks

My mom gave me these quilt blocks about a year ago. They were one of her unfinished projects that she wanted me to finish. Neither her nor I were fond of the colors, so I ripped them out and started again. Well, I ripped out the light pink and used a blue instead. Now I have had them in my unfinished project pile for a year and I am finally on my last block. The only trouble is that I am not sure what to do with the edges. Sorry, I didn't get a good picture of it, but there are smaller blocks arouhd the border of each block. I am not sure what color or colors to do these in. I am thinking that since there are only six blocks (I can picutre your jaw to the floor. I know what you are thinking, "It took her a year to even get close to finishing these, and there are only 6!" I know, I'm in shock too) that this will most likely turn out to be a wall hanging. I was planning on getting cordinating fabric to make sashings but I'm not sure about that now. So, I guess the point I am slowing making is that I need help, major help. What colors should I do for the borders of each block? Should I put sashings between the blocks or not? Should I try to find more blocks of the same pattern and make it big enough for a baby quilt or twin size quilt? Just teasing, that last question is not an option, I'm so ready to be rid of this thing. Help me!
