Not sure if it's the brushes or the brand of acrylic paints (DecoArt or Martha Stewart Satin Finish) I use, but I'd like to achieve a smooth finish when I paint my ceramic pots.
A few options:
- Watering down the paint (as mentioned in the comments) Acrylic paint can be thinned by adding water until brush strokes self-level. If you want to be uptight, use distilled water. Chlorine and minerals in tap water may have some effect on the paint, but it's doubtful that it'd be significant.
- Foam brush Foam brushes are often used to avoid brush strokes. You used the word "delicate" in your question, so this may not be an option.
- Spray Painting (with stencils). Depending on what your art is, you might be able to create a stencil for it and then spray paint. You can buy removable self-adhesive vinyl from a crafting store (electrical tape works in a pinch) and either cut it manually or find someone with a computer driven cutting machine like a Cricut or Silhouette.
