Cross Stitch Project Advice?

I have done many cross stitch projects in the past, but I have never done a blanket before. I have just found out I am going to be a grandmother so I decided to do a baby blanket. It is quite a large project and I am running into some problems. I am concerned because as I work on it some of the stitches are starting to look kind of fussy and worn. I admit I am a bit of a perfectionist and I am also worried about it needing to be washed repeatedly. I assume that it probably should be for show rather than use. I am concerned that the stitching will come undone when washed. Also it is a kit and the blanket is quilted so I am wondering if I could sew fabric to the back once it is finished so the thread work doesn't show.

Also I am used to using hoops with smaller projects and I am not sure what frame to try. I looked for a scroll frame, but couldn't find one to fit. I bought a snap frame, but I have to keep moving it around because it doesn't fit either and is awkward because of the left over material hanging off. I have never had a problem sorting out the colors of thread, but this time they are not labeled and I am having a heck of a time figuring it out! Any advice would be greatly appreciated!
