Message: WHat type of white t-shirt is best? 50/50 or 100% cotton? My daughter will be doing this at school and I want to buy the right kind of shirt. Thank you!

100% cotton. Polyester is very difficult to dye and will remain white with most fabric dyes.

The result of dyeing 50% cotton/50% polyester is a combination of dyed cotton and undyed polyester, producing pastel colors. This is not necessarily a bad thing, so if you have a 50% cotton shirt, there's no harm in using it. For very bright or intense colors, a higher content of cotton or other natural fiber is desirable.
