slammer 0 Report post Posted January 18, 2010 Hey folks Is there any "rule of thumb" on what closed cell foam size to use on what hook size? For instance would you use a 2mm foam on a #14, 16, 18? The foam would be used possibly for a nymph wing case. Thanks! Quote Share this post Link to post Share on other sites
Firetiger 0 Report post Posted January 18, 2010 For nymph wing case I use 1.5 mm thick black foam and it seems to be working out nicely. 2 mm would be OK as well, but much thicker than that will give your fly a very fat head. I don't like those Quote Share this post Link to post Share on other sites
