Getting started in a new hobby can be expensive, but it doesnt have to be! You only need a few tools to get start with paint embroidery.
Essentially, you really only need paint pens and your project piece, but if you are going to go past flat cotton fabric and drawing doodles you'll need a few more things.
embroidery patterns- If you aren't great at freehand, this is a given
paint embroidery hoop- It keeps you fabric steady, and makes it easier to apply paint
Knit sticker- If you are doing knit fabrics (like those soft cotton t shirts)
Honestly it does depend on what projects you're doing as well, but this is a good start. I wish trichem had better pictures, something I intend to change once my stuff arrives (which BTW I'm expecting any day!!!!)
