After throwing a masstve strop over not being able to get the frosting to look right I went to work in a huff and my ex husband took the task of getting this right for me.
he used 2 camping mats (from poundland) glued together with hot glue and heated them with a hot air gun until they were soft, then he molded the edges to drape over the corners as it would do if it was a fondant.
I’ve got to hand him the credit on this part, he done good.
