I've made jelly roll quilts with strips going top to bottom just for this reason ..... one that was even 78" long for a tall guy. I don't know why you can't make them any length and width you desire, you just have to add strips together to get the length you desire. I look forward to seeing your finished quilt.
Added note: I'm not good at estimating how many strips I will need or I may change my mind while sewing so I cut a bunch and start sewing, then cut more as I need them. It works for me.
