Paper foldables were a big hit at the ASEconf. This web-page is as good a summary of available resources on the topic. I find students really like these. When given the option how they create notes an increasing majority are opting to use these.
Look out also for resources from Dinah Zike who seems to be the doyenne of foldables in the US, here is one of her pdf booklets

A huge list of resources for revision and ideas for learning in different ways.
