I usually use the Bernat yarns. Once in a while I'll use the Caron yarn if it's in the color I'm looking for. I just looked at the yarns I have and I have some Red Heart yarn besides the Caron yarn and Bernat yarn. The Red Heart yarn seems softer than the Bernat or Caron yarn. Do you like to use the Red Heart yarn?
I also have some 'Soft Secret' by Yarn Bee'
