the ribbon that goes around the cake - where DO you buy it??

[OhCobblers]

i'm not the best cake maker in the world (i've made about 3 larges ones in my life ).
i need to make a celebration cake soon and thought the ribbon that goes around it would hide a multitude of sins - but apart from very expensive cake shops can i buy it anywhere else or is it Ebay for me??

TIA

Hobby Craft / Local Haberdashers or John Lewis will all do it
or Ebay it

My last lot was bought from Hobby Craft but thats because i am very last minute and also I like to feel what I'm buying
