re: Cholla and epoxy bedside lamp

I used a no-name brand (Shabebe) to do a fill on a table for a friend.  It was not their deep pour variety but I went about 1/2 inch deep with no issues.  Not the same as what you did but deeper than 1/4".  The stuff was much cheaper than the name brands and I was very happy with the results.  If you are up for some experimentation, their deep fill version claims it can be 2-4" deep.  Unfortunately, it only seems to be available on Amazon.
