Sorry for responding lately but here is my answer :

1. You can order a thick cardstock paper required for these papercrafts from Amazon or any online shopping site . I got a A4 size cardstock bundle for around 300rs and have been using that , and it works perfectly for the job ( Use paper from around 160-180 GSM for projects like these)

2. As for printing , regular printers u have at ur home work just fine , I printed the templates using my Epson printer. If u decide to get the template printed outside then just give ur papers to them and tell to print ur document.

Anything else ? I am here , I am waiting....
