This list of providers of custom t-shirts came off the Techfriends slack where someone asked about vendors that handle small runs of custom t-shirts.
I have no experience with any of these. Some folks had some comments, which I paraphrased and added.
- Custom Ink
- Scalable Press (used to be shirts.io)
- A Small Print Shop
- Black Collar Printing (quality vouched for)
- Handlebar Mustache (local to Boulder)
- Burts (local to Fort Collins)
- Jack Nadel (larger scale)
