I just posted my first three submissions to threadless, and I am pretty stoked. I do not know how hard it is to get your submissions accepted, but I feel pretty confident in my first three submissions. I do not know how much promoting you have to do. I am not very social when it comes to the internet, but I guess it is time to learn some new tricks. If anybody out there has any advice about getting your submissions posted when you are not a facebook , or twitter type person, it would be appreciated. Anyways good luck with all of your submissions, and any advice you could give would be great.
