I only buy jelly rolls when they are on sale and most of the time there is yardage to go along that I will also pick up. I made a king size log cabin years ago but I am pretty sure that I didn't use 7 or 8 jelly rolls. Is there any way that you can do a search to try and find the fabric that is wanted maybe you can find it somewhere that there is no limit on how many you can purchase or as I said you can pick up the yardage as well. Good luck!
