Love them, may have to try something like this myself if I can find an iron Btw, how long do you spend on making one, just thinking that $5 sounds like very cheap compared to the amount of work needed and the raw material (beads).
the corkboard was like $6 for like 6 sheets and i can get 4 coasters cut from each sheet. not that many beads were used, these are only like 3-4 inches in size. and to actually place the beads and iron them takes about 15 minutes. i work fairly fast.
i sold the set of 4 SMW for $25 (that included shipping) and the set of 4 ff6 for $30 (included shipping and also cost a little more since they are bigger)
