Working with MinkyMinky is a very popular fabric choice for making plush ponies, and MLPPlushies has an article on working with it: http://mlpplushies.deviantart.com/journal/Tips-and-Tricks-Working-with-Minky-319075769Personally I prefer tacking to pinning, since minky is so thin the pins distort and pull the fabric. You can also use clamps or paper clips (although paper clips also tend to fall off). I also always back minky with iron-on interfacing, to make transferring the pattern easier, and to keep it from slithering, wrinkling and stretching quite so much.Any other tricks you'd like to share?
