Hi there. If you can identify which cake you are talking about, perhaps we can help. You can get a woven look on a set buttercream by using a paper towel impression, an impression mat, material with a pronounced weave place on the set buttercream, various methods.

I did not see the picture of the cake on this website. I just remember that the person showing me the picture said they piped the buttercream icing on top of the cake to make it look like a blanket. I can't remember the tip they said they used or the technique. Any ideas would be helpful. I am pretty new to cake decorating, so I need lots of details. Thank you so much! 
I wonder if it's the same method I've seen used for sweater-shaped cakes or Wilton's crocheted-look 3D teddy bear? This method involved using a round tip--probably a 3 or 4 and creating small overlapping loops. Very neat the way it comes out but I bet it's time consuming!
Skylar,
I have done several baby shower cakes with what I think you are talking about. I place a baby that I get out of Sweet Celebrations pg 54 in the catalog on the cake and then I take a piece of saran wrap and fold it in half so it is double thickness, maybe about 10" wide after I double it. I lay it down on the counter and then do the basket weave technique in 2 different colors. Then I gently lift it up and place it over the baby making sure to come over the head a little so it doesn't slip down over the back of the baby. After I get it draped into place I leave it with slight "folds" in a couple of place so it isn't just flat, and then I pipe a border around it to cover any saran wrap and give it a finished look. If I knew how to attach a photo to this I would. I hope from my jumbled explanation you can figure it out!!

Well it most certainly could be any of those methods. Some people use the star tip and make the blanket look like a patchwork quilt also. I was thinking of the sweater look when you mentioned it. Of course the easiest method is to use a pice of rolled fondant and imprint it with perhaps Viva paper towels that have that woven look.

Hi--
To expand just a bit on SquirrellyCakes' suggestion of using rolled fondant, I would take a texture sheet (found in craft stores in the polymer clay department: don't worry, they are food-safe) and use one of those to get a quilted look on the fondant. I have a set that includes a woven, lace, and floral pattern.
Luraleigh--it is very easy to upload a picture on to this site. Make sure you are logged in, go to the galleries page and click on "upload photo." The site walks you through the process.
Good luck!
Hi Skylar,
The cake I did in the picture gallery with the small bear on top of a square has a fondant blanket.I used a tracing wheel to make the squares and stitches and cut out little flowers for the inside of the patches.It was really easy!! See my Profile under my name!!
Hi Kiddiekakes,
That cake is gorgeous. I haven't worked with fondant very much, my family doesn't like the taste. I have tried the trick of adding vegetable shortening and vanilla flavor, but they still did not like it. Do you have any secrets for making it taste better?
Thanks! 
I depends on the fondant.My mom gets a certain type of fondant from her supplier and it tastes and smells like Candyfloss.Wiltons does not taste good!!Have you tried making a Marshmellow fondant?? It is made with marshmellows and taste really good.I think there is a recipe for it on the wilton forums if you do a search.That might be an option!!
Skylar,
Have to agree with you, every cake Kiddiekakes does is perfect, she is one talented decorator! And a super nice helpful person too!
