Thank you ClearlyCake for your input. I have had situations, where i had to cover big cakes – 26’’ & 30" both 4" tall, so I use a size 33 × 27″ formica counter top. The 24 × 18″ non stick board will be too small .
Have watched the YouTube clip on using the mat by Sweet wise. Will try my hands on the Mat as recommended- the Pro mat of size 30 × 30″, should suit my requirements size wise.
My sincere gratitude to every one who took their time, to point me in the right direction.
