fabric stiffener spray on felt???

[cchavez]

So DD and I are making her a hedgehog costume....we used felt for the "quills" like they did here....http://www.etsy.com/listing/108316937/fairy-tale-hedgehog-costume-party?utm_source=google&utm_medium=product_listing_promoted&utm_campaign=children_mid&gclid=CI3pq8PC_bUCFWGrPAod5TsAIQ

But we also cut the ends into fringe....I was wondering if I used fabric stiffener spray on the felt...would the quills stiffen and stand up? Any ideas? Suggestions?

Thanks!
