This listing say iDye Poly in the main listing, but says it is only for cotton? Please explain or revise your listing?

this is for synthetic fabrics. If you have a blend of natural/synthetic fabric, it will only stain the synthetic fabrics, yielding a lighter version of the color. I used this on a pink sweatshirt that was a poly cotton blend. THe black ended up being a medium grey, which is what I set out for. If you have a blend and you want the fabric to dye fully, you will need to use a mix of this product ant the iDye that is meant for natural fabric.

i have a red fleece poncho...will the black poly dye it correctly?

I doubt it. I tried to dye a dark yellow dress black and it is olive green

Can I use this for tie dye? Meaning mix small amounts and different colors and use them from squirt bottles?

Not exactly. Heat is 100% needed for this product to be set in the fabric. You can iron the fabric after the dye has dried after you squirt it on, but that is incredibly time consuming. You should steam instead. Take a look at these DIY steaming instructions. https://static1.squarespace.com/static/5ac4eb022971149bb6d709d3/t/5b3e48858a922db5a565bfc0/1530808455316/Make+Your+Own+Fabric+Steamer+Instructions.pdf
