Hi! It's my first time using fabric paint and I could use some advice. I bought Jaquard Textile Paint, raw umber color, it looked fine after painting and heat pressing but after a wash or two it faded out to a more grey color. Maybe I messed up on a step or maybe it's the material of the hoodie/wash? It did say semi-transparent so perhaps I just need more layers? Here's an image of the color after painting & drying; And an image of the color after a wash;
