HeffnerMM and M would be good for this! They both use TF piggies. I'm awaiting for some samples to come in the mail and I absolutely cannot wait. I can tell you that the staff is really super nice though!
I've tried these before I just didn't like them. I am really picky when it comes to my e/s or pigments. I know plenty of people that like TF but for me MAC pigments = true pigment love for me.
I love Twisted Fayte pigments. They have a huge range of colours and the textures are really easy to work with. They also work out a lot cheaper than MAC pigments.
Plus the owner Heather, is great. For customer service they cannot be beaten.
