I am looking for a source for the larger clear plastic snaps that are used on wedding dresses, usually they are used to hold the panel in place that is beneath the lace-up on the back of the dress. These snaps are usually round (though I have seen square ones) about 1/2 in diameter, unlike the tiny plastic snaps that are easily obtainable. If anyone can tell me where I could order these kinds of snaps i would be so grateful
