Thanks all, for the feedback and suggestions.
I think $7 is quite reasonable for the size 10tonvinyl described, since I think he is talking about single-color custom cut vinyl rather than printed vinyl stickers, although I can see the desire to have both. For my board, I probably would prefer a printed sticker with a contrasting border to be make it visible against my topsheet which looks like this
, but against solid-color surfaces like my car window cut vinyl looks classier.
Thanks Cr0, I think the crail grab might work really well, though I'm also afraid the other method will be difficult to decipher as a silhouette, but I might give it a try. I will work on those when I get home later. While I drew the current method freehand, it was loosely modeled after this pic of Pat Moore
Also, thank you Leo for starting this whole thing
