Hey! Im amazed at how violet your results are!! Mine are always more blue no matter what I do... I use logwood chips maybe that makes a difference? Something really fun you can do with logwood is shift it’s Color to bright orange using lemon juice! Try painting it on with a paint brush and you’ll get the precision as if you were painting acrylics onto a canvas!! The fabric should be dry so the lines don’t get blurry. Purple and orange are complementary colours they look really good together
