LoyalNine Report post Posted August 4, 2014 (edited) so I have been reading the forums and trying to learn more about Thread, Thread sizes, SPI and every other detail related to learning to stitch by hand it still remains a dark art to me. I stop by Maine Thread company today to ask some questions I didn't get all the answers but I did get some thread they had a bargain bin - not bad 20 rolls for 10 bucks I'm not quite sure what I have here apparently the wax thread is sized by the "ply"? I'm not sure how that relates I had not read about thread sized that way before when reading about it in the forums. if I wanted to make a wallet what would be the appropriate size thread with ply using 7spi? more confused now than I was this morning! 😃 Edited August 4, 2014 by LoyalNine Quote Share this post Link to post Share on other sites
Hi Im Joe Report post Posted August 4, 2014 for 7 spi I would use .030 or around there. Quote Share this post Link to post Share on other sites
LoyalNine Report post Posted August 4, 2014 Thanks for the reply. This I guess is my confusion... There are no markings indicating what diameter the thread is. All I can do is tell how may ply it is by examing the end. Does the number I ply equate to a diameter or is it different for all manufacturers ? -Joe Quote Share this post Link to post Share on other sites
dbusarow Report post Posted August 4, 2014 (edited) The Maine thread I have has a label on the inside of the cardboard core. It lists the diameter in inches, e.g. 0.040 Dan Edited August 4, 2014 by dbusarow Quote Share this post Link to post Share on other sites
LoyalNine Report post Posted August 4, 2014 This stuff is not marked on the inside. It's seconds because of color or the way it spoiled on the cardboard. Apparently they Mark it at the end. The seconds never get marked. Maybe I'll email them to find out what ply thread equates to diameter. Quote Share this post Link to post Share on other sites

That way you can at least find the look you are after. Quote Share this post Link to post Share on other sites
billybopp Report post Posted August 5, 2014 This might help: About 4 messages down ... http://leatherworker.net/forum/index.php?showtopic=55977&hl=%2Bthread+%2Bsize+%2Bchart#entry359041 Also: http://www.tolindsewmach.com/thread-chart.html I'm pretty sure I saw a more complete thread size chart somewhere recently, but darned if I can remember where it was. Hope that helps anyway! Bill Quote Share this post Link to post Share on other sites
LoyalNine Report post Posted August 5, 2014 Thanks for the replys. I emailed Maine Thread this is what they gave me for an answer: Approximate: 2 ply = .5 mm 4 ply = 1mm 6 ply =1.5 mm Quote Share this post Link to post Share on other sites
