Further to my prior post “viewer discretion is advised” I have another one! This one is a muppet-based creation.
Flannel and flannelette are great fabrics to use for this because they’re stable (ie: they don’t stretch) but also because they’re soft and fuzzy and usually 100% cotton. Just make sure you always wash and dry your fabric before you use it! I dry my clothes on delicate and dry my cotton fabrics on HIGH – sometimes twice! – just to get as much shrinkage as I can out of them.
