And fabric choice (all items just MHO):
- Thin fabric tends to print more; thick fabric tends to print less. (In the wintertime, lined flannel is virtually "printless".)
- Fitted shirts tend to print more; loose shirts tend to print less.
- Rayon, nylon, and silk blends cling as they drape and tend to print more (can you imagine if we were back in the disco era trying to conceal under tight, chiana shirts?); absorbent fibers like cotton and wool tend to print less (a caveat is that some rayon/polyester blends are woven thick, for winter wear and don't print easily).
- Simple, geometric patterns like vertical lines tend to print more; complex patterns tend to print less.
- Light colors tend to print more; dark colors tend to print less (contrast between light and shadow isn't as evident).
And welcome aboard!
