pattern adhesive

[ToddW]

I saw some youtube video's where the guy used some sort of contact cement to temporally attach the patterns to the leather.  I think it was GS Bond which you can't get here and he only put the glue on the paper pattern.  I have also seen pattern glue such as this:  https://www.amazon.com/June-Tailor-JT-443-Temporary-8-2-Ounce/dp/B00KHFJG0S. I saw some woodworking guys using the 3M spray like the glue on postit notes.  I like the idea of putting the glue on with a spreader vs spraying it.  Anyone have a suggestion on putting a pattern on leather without residue when you pull it off?

place the pattern on the leather, use brown paper shipping tape over the pattern, and let it stick to the parts of the leather that you are not going to use

see tis video,  skip to 6:16 of the video  too see how to mask

Do NOT use double-sided adhesive tape from a leather shop. It is meant for sticking leather together prior to sewing and won't pull off cleanly. Guess how I found that out?

You might try something like contact paper.

I just use cheap £-shop masking tape. Its not too tacky, but to reduce it even more I put a piece on my trousers first.

I also have  Frog 'Green' masking tape which is very low tack. Frog 'Yellow' is tackier

Standard technique for me is to spray on a light spray onto the back of my pattern and let it air dry for at least a half hour. Here is a link to a project I did awhile back that gives you a fair explanation.

If you check my profile section in the "about me" part you will find a few more similar ones to this as well.

I don't attach my patterns to the leather.  i will make it out of paper, then will transfer it to a manila folder by tracing it.  Or i have some very thin (.03125) plastic sheeting I will transfer it to.  I will then place this on the leather and hold while tracing.  If it is a large piece I will use a weight to hold it in place as well.  Here lately, I have been flipping the leather and placing the pattern upside down on the flesh side so I can trace with a pen for better marking than using a pencil or scratch awl on the top surface of the leather.  May not be the best way, but seems to work well for me.

On veg tan one can put a dab of solvent based contact cement on the pattern and wait until it is tacky then apply to the leather.  First test on a scrap.  On chevre and some chrome tan, I use double sided tape.  I've never had an issue.  On my veg tan I use a poster board pattern and use Scotch tape.  I cut right through the tape.  Sometimes I'll add a binder clip to a cut side or two.  I prefer the two tape methods best.
