RKCrowe Posted June 22, 2015 Report Posted June 22, 2015 Good day to all, I am new to leatherworker.net and have really enjoyed it. So much info and talent here it's kind of overwhelming. Anyway, I am making a koozie for a 12 oz. can, it's going to have a 2mm foam sheet lining. The leather I am going to use is 3-3.5mm. So after hurting my brain relearning some math, I cut some test pieces of foam and leather and test fitted...I sat back and scratched my head and went huh! The fit was almost perfect, the leather ends butted up nicely, However, I meant to have a 10mm overlap to glue and rivet. I gave consideration to the thicknesses of foam and leather, My question is; Is there a formula, rule of thumb, etc. to determining dimensions for cylinder projects like my koozie? Quote
Members Wild Bill46 Posted June 22, 2015 Members Report Posted June 22, 2015 Sorry; RK I'm not going to be the Talent your looking for on this project ! I'm in the exact place as you, (so to speak) ! Last year I wanted to make some stylized-and personalized Coozies myself. As Christmas gifts to pass out among family at the lake. I began , but never completed my projects, I just had too many other projects ahead of this ! But I'm sure ! the Talent is here somewhere among this diverse group ! --- Wild Bill46 Quote
Members Halitech Posted June 22, 2015 Members Report Posted June 22, 2015 (edited) usually I will cut a bit longer then I want then dry fit and cut again if needed. Personally, I like the butt fit with sewing over a rivet edge. Edited June 22, 2015 by Halitech Quote Every day you learn something is a good day.

Members DavidL Posted June 23, 2015 Members Report Posted June 23, 2015 illustrator Adobe or photoshop can figure that out for you. Plot out the pattern on offset the pattern by the thickness of leather (ex. add 2mm around the perimeter of the pattern), use some setting in the program to measure that line. The other way is to do it by paper and measure using thread. I never tested this but it should work more or less, the stretchiness and stiffness may affect this? Quote
Members Jim Posted June 23, 2015 Members Report Posted June 23, 2015 The solution is actually right in front of you as it was with me. With the varied thickness of leathers used and the folds, the bends, the twists . . . no wonder I don't have any hair left! Oh, sorry . . didn't mean to get off track. The answer is to use a 1" wide strap of the intended leather to wrap around the foam to determine the length or width of the leather for the project. Once wrapped around, mark the spot on the strap that gives the needed over lap and then measure this mark from the end of the strap. I used this method for measuring everything from wrists for Cowboy Cuffs to coke cans for Cowboy Coozies. It works.

Members Jim Posted June 23, 2015 Members Report Posted June 23, 2015 To give you an idea of just how useful the Strap is, everything shown here was first measured out with a strap of the intended leather. Then the pattern making began. Quote Never forget where you are, so you will always remember where you've been.
RKCrowe Posted June 23, 2015 Author Report Posted June 23, 2015 I would like to thank all for their suggestions and support. I stumbled onto this site and I'm not letting go. I thought I had worked out a solution, but no, it must be a math formula above my pay grade so… I will use what I learned from you. Jim, awesome work there. On use of the strap; on the not so round projects, you just brought the strap around until it met back with itself and added some for the stitching? Thank you all again and good day! Quote
Members Jim Posted June 24, 2015 Members Report Posted June 24, 2015 Actually the strap is cut longer than the actual length (width) of the project would require. This way you can figure the needed length including the stitch or rivet line. When you start trying to figure distance and then adding or adjusting for stitching things will more often than not go horribly wrong.

RKCrowe Posted June 24, 2015 Author Report Posted June 24, 2015 Thanks again, I will try your suggestion. Quote
Members Jim Posted June 24, 2015 Members Report Posted June 24, 2015 I'm thinking real hard about writing a tutorial on this. Might help some folks keep their hair on their head longer. Jim Quote Never forget where you are, so you will always remember where you've been.
