i got heaps of ideas on how to solve my wrinkle problem - thank you so much everyone! i even got a powerpoint slide with a whole heap of recommendations :-)
to try a fix as quickly as possible my first try will involve using a different metal ring - the metal is thicker. let's see if that already makes a difference.
i will get different strap material on monday. the sample piece that i have looks thicker! that will be try number 2 then. as the webbing will be send to melbourne for tinting, my try number 2 might be delayed .. or i just cut a bit off the roll to try it ..
the ideas i got on how to solve my 'wrinkle' problem and some initial comments from my side:
- run a line of stitching along the top one like you have the bottom one to fix it in place.....could that work?
a: the strap should still be adjustable, if i run stitching along both sides that would no longer be possible. i'll keep it in mind however, the fix might come in handy in another spot :-)
- change the angle at the bottom - line it up with the force involved (so the metal is perpendicular to the angle the strap ends up)
a: if i want to use a wide strap from a design perspective it would be all wrinkled in the narrow end. mmh, i'll think about it
- put in a pivot like you see commonly on computer bags
a: a pivot has been used on another bag that i purchased a while ago. if i can find the right kind of metal pivot i will give it a try!
- move from a rectangle to a circle so is less noticeable
a: circle .. haven't considered that option yet ..
- or a semi circle - flat side for wrinkle free, curved for the support (basically another form of the pivot)
a: saw another bag with the semi circle option - it also moved and encountered the same problem as my bag
- more narrow metal ring
a: something i have been looking for for a while .. i just cannot seem to find any :-(
- webbing and metal ring wider
a: the webbing/strap is 50mm - that's as wide as the standard sizing goes
- reduce inner radius on metal ring and ideally make it square
a: i hope to apply this idea in my first wrinkle. my metal ring is not square but has a reduced radius due to the thickness of the metal
- use webbing/strap that is stiffer
a: hopefully the strap material that i want to use is as stiff as i imagined it - it should arrive monday!!!
- enhance webbing/strap in the area that goes through the metal ring
a: last resort, but has been the approach on another bag i own
- use a strap with higher stability against lateral deformation, e.g. a leather strap, which is thin and soft enough like calf leather
a: i hope the new strap material has a higher stability - let's see how it performs in user testing :-)
