Gingerbread House Ornament

This post is more to share an idea than a finished product. Because the finished product didn't turn out too great...but I still like the idea!

Having made gingerbread men ornaments I thought a gingerbread house ornament would be fun, and you know how I like making miniature buildings.

I made some simple houses out of card and put a loop of gold thread between the roof so that they could hang.

I painted the houses with acrylic paint. The colour may have been the first mistake. It looks maybe a bit too orange for gingerbread.

For the icing/frosting detail I wanted something three-dimensional to replicate the real stuff.

I found this big tube of filler for 99p and thought it might be perfect for the job.

My Mum made me a piping bag out of greaseproof paper and I squeeze some of the filler in.

The piping in this photo isn't too bad, but other areas were a hot mess.

My piping skills aren't that bad - see last years actual gingerbread house - but the filler is thicker than icing and doesn't flow as well.

 This is what I ended up with.

I think the cardboard is too flat/lacking texture compared the filler which is maybe too big for the scale of the houses.

Any ideas for alternative ways to do this?

Or any other uses for the filler now that I have a whole tube of it?
