Didn't get any responses, so I thought, I'd give it another go...
I'm not sure, but I would probably do the bear in fondant pieces/cutouts and then paint the plaid on in watered down colors
I like what your trying to achieve it seems like fun! This looks really tough, and I've have not even tried to do plaid. But here are some ideas.Cover any baked and cooled cake with a smooth layer of fondant. Hold a thick- or thin-stripe stencil over the cake and spray with a mist of cake coloring spray. Have fun and hope it turns out great!!!
I am thinking that you use a black edible ink pen and of course use a ruler to get them straight but I would think that the fondant would have to set up first so that the pen wouldn't dig in the fondant.
Thanks so much for the ideas! I never thought about the edible marker and spraying a stencil. I love this website!
You could also easily iron on a plaid chocolate transfer sheet. It's nice because you can stiil smooth the fondant.
http://www.americanchocolatedesigns.com/ has several different plaids.
Please tell me more about ironing on a plaid chocolate transfer sheet
What about using an edible image?
I've done a couple of plaid cakes. Both were piped buttercream, with the lower levels of lines smoothed gently with a Viva paper towel. It's not difficult to do, but looking back at these now, they could have been neater. But here they are as an example:
Aine2 has a how to video on her website. i will try posting the link, it is just after making a tiara....
It turned out great!!!!
It looks really really nice, I think it's great!!! In fact I am adding it to my favorites.
Great representation!! I also was thinking edible immage. That way you were not limited to the preprinted plaid selection or the costs. Congrats!!
