You can use simple cardboard tubes, sturdy, thicker ones are best, with elastic bands or sticky shapes. Try different widths of elastic bands, string, rick rack or anything with a flat surface that you can adhere to the tube.
Rolling pins that have been carved in patterns are also an option as are foam rollers, used as is or with elastic bands or string pulled tightly to make an interesting surface.
Remember that I'm usually cutting out areas from the fabric, rather than using it as an entire piece, perhaps even cutting it on the diagonal....
These are all simple but so effective...you can probably think of many options!
