While it’s always important to check your manufacturer's instructions on compatible products, there are a handful of t-shirts that are ideal for most iron-on transfers: 1. Preshrunk t-shirts in cotton or cotton/poly blends - you don’t want to drastic shrinking to warp your design or make the shirt unwearable 2. Gildan’s G64EZ0 Adult Softstyle EZ Print T-Shirt - it’s literally made for printing projects! 3. Enzyme washed tees - dye is broken down into smaller molecules that wash away easier - leaving a super smooth printing surface that materials bind well to. 4. Combed and ringspun cotton - so incredibly smooth to the hand and even more comfortable to wear!
