What I did was score each line very lightly and fold it using a metal ruler. Put the ruler on the line, fold it over the ruler and crease it with your fingernail. Hope that makes sense/helps
I know it is hard to see on my pic, but there are 2 mountain and 2 valley folds all the way across. As you can see by the pics.....My fingers are huge as compared. I have tried 3 times with a ruler and end up mangling the piece. =(
i score the lines with a metal ruler and a flathead screwdriver(woorks for me) then i use a pair of tweezers to make ubersmall folds... or needlenose pliers...
I hope they work for me, I went into the woman's drawer and it looks as though she may have taken them with her......Awwwww poop! Off to storage to find my needle nose.
Have you tried an Exao knife to get the lines to fold smoothly? When i need to fold small detailed lines i'll cut semi-deep along the lines and it folds well for me.
