Could it be your brush? I've recently changed brush and it's made a huge difference. Maybe upload a picture so we can see what it looks like and then someone maybe can tell you where you are going wrong.really struggling to getting the shape with acrylics. I have to file so much cos of all the bumps
I'm no expert as only qualified April but firstly they look lovely! I would say if you've done good sets previously then maybe your bead was too dry or you applied it too thick.. maybe you weren't able to smooth it out and work with it before it dried. Oh and have you checked your acrylic brush to make sure it hasn't got any acrylic dried in it as this will mean your finish won't be smooth??.xyeah I've changed brush but it did a perfect set yesterday no filing needed. Then today there was lumps and bumps all over.
