More help with Spike's Costume...please =)

[dolphinsilversea01]

So, you all have previously helped me with ideas about Spike's costume.
I did some looking and all the mustache tapes look and read the same as two-sided tape, so I'm just going to use that (hopefully it will work).
I have come up with another part dillema - what to use as the base of the mohawk wig to keep it together. I was thinking of using cardboard; it's strong and sterdy, the tape and glue will stick to it, plus it is a little flexible so it will bend with his head.

What do you think?

Thanks
