While there are tons and tons of fabric, leather, trims, hardware (and the list goes on), the options are also interesting in terms of quality. Velcro and elastic bands come in a variety of different standards (typically low, medium and high). It can’t be taken for granted that magnets have sufficient magnetic strength either. You get the picture!
Learnings of this trip so far? Never take any aspect of your product for granted and test every single thing! (An example based on experience – don’t assume that buttons provided actually work). That said, I would love to move here to gain access to the very many resources that would make life so much easier! :)
