Shiree ... Welcome to the QB!
While it only does hexies, that would still give you a pretty good idea how the 8-sideds would look.
I'm old school ... and just go with two mirrors stood on end.
Just by moving them around, you can see assorted # reflections to get a sense
as to what an end result might be like.
Mine are just a pair of school locker mirrors, duct taped together ... from the $ $tore!
Actually they are better quality mirrors than the "official" quilt store mirrors .....
and considerably less co$tly!
