I prefer the flat waxed nylon myself but you definetly want a heavier denier than standard sewing thread and if you are stuck for a quick sewing thread for a temp use ZAP IT glue over the threads helps alot. Craft fur isnt to bad at all it takes a little getting used to from cutting a peice off from the carpet type holder lol I prefer the real hair myself but everyone does have theyr favorite to work with .
