Cut from 3mm mdf.

PLEASE NOTE: 

If you choose 'Son' the wording will be:

Excuse the mess my/our son is busy making memories

If you choose 'Grandchildren' the wording will be smaller as there is more of it on this design and will read:

Please excuse the mess my/our grandchildren are busy making memories

All others will be as shown in the picture.  The differences are to allow for the size of the words.
