Cee Kaye you are completely legal, I did the same in the jewelry manufacture business for many years, you do not need a work permit for that as you pay Thai shops for making your design. I am verysurprized that even the moderator of this group (

) shared the same view as the scaremongerers. Regarding your travel plans, I would apply for a Multi Entry 6-months Tourist Visa (METV) in your home country, as this visa type allows you multiple exits and re-entries for the whole duration of 6 months, each entry getting you stamped in for 60 days, and every 60 days can be extended on Immigration for 30 more days for 1900 Baht.
