My friend at work got hit by a drunk driver and many ppl have helped her out the last few weeks. To say thank you she made coasters and I just made some following her instructions.
What you need:

Some kind of backing (felt, cork board which can be bought in squares at Hobby Lobby or in sheets from Home Depot)
1) you cut squares with the paper you chose
2) use the modge podge to paste on the paper then use it on the top
3) spray the top with the finishing spray
4) with a hot glue gun, glue the backing you have chosen
