Always so many different suggestions, aren't we lucky! Last night I attended a local performance put on from home schooled students.... 7 wives for 7 brothers..... in the one scene we have the single beds for the girls.... all had very simple quilts on them.... all made with perhaps a 5 or 6" square of scrappy type colours..... they were very effective.... all 6 in the one space. Just squares stitched together.... a gentle reminder to myself that sometimes "less is more" ..... maybe something like that would work for you?
