OUCH, wrong answer.
One thing I've heard from a number of friends & coworkers that have given money to Kickstarter campaigns that have gotten full funding (for various things from comic books "ready to print!" to tech to apparel) is that they all have one thing in common: the end product always always always always always always gets delayed by months from the campaigner's unexperienced estimate.
Now, looking at your Kickstarter page, is there anything here that you need Kickstarter for that you couldn't have already uploaded to
Cafe Press (for multiple shirt types & misc other things like coffee mugs) or
Spreadshirt (not just for the shirts anymore either it seems) and made available to the public to order TODAY?
I like your design of the star-spade. But it's just one clip-art-like image on the front of a shirt, nothing special going on; no fancy sleeve pinstriping nor UV ink splashes along the bottom wrapping around the sides. I could design that same image in Photoshop in 5 minutes (Photoshop's built-in "Custom Shapes" tool features both the classic 5-pointed star as well as a spade) and then upload to either of those sites. [I won't, I promise! That's not how I live my life.]
Also, a bit of marketing advice:
The last image on the page is the header for the section about
the description of the shirt itself. The image features a
topless girl.
"Sex sells" I guess is the cliche motto? But you're not selling sex. You're selling shirts. I want to see the
shirts, front & back, and on multiple models not just the skinniest ones. What will this shirt look like on a 200lb woman? What will it look like on a 300lb middle-aged man (you know, most local magicians! sorry couldn't resist, it was from something Chris Kenner said in a lecture once a long time ago!)
Well, GLHF!
