I've been using light transfers on white shirts. I'm waiting for my dark transfers to arrive so I'll start on the colored shirts when they do. I found Hanes perfect fit relaxed fit T's on clearance for $1 each at
Walmart so I got a bunch. They also had a ton for $3 each so for the girls and myself we are good. Not a single mens/boys plain T to be found though!

So I'm going to have to expand my search a bit.
I have sooooo many designs that I'm having a hard time picking the ones I want to use for this trip. I've got 15 shirts done/half done already with a ton more to go (9ppl on the trip). There are only 2 that I'm doing for everyone so 18 there and then I have a bunch for the kids that I'm doing and some for the Christmas party too. It feels like I've bitten off a bit more than I can handle with our limited space here in the house but at least I started months in advance. I still have 2mths to finish everything up.
Don't forget to read the "20 steps" thing. Mostly about setting the ink with the vinegar. It's really important or else it will run all over the place if it gets wet at all. Here's my added hint....dont' put red/pink/orange colored transfers in with the rest! LOL
