Here's one of my cards using the number stamps from Lesson 13 of In the Classroom with Barbara Gray. I'm not quite sure where the idea came from but this is what I came up with. :-)
It's a good job that Mum and Dad were here when I was planning it. Being a crafter, rather than a bingo player, I was thinking of the bingo cards that you get as embellishments. As with a lot of craft things they are American. I didn't realise that British ones are different.
After a quick Google I found out what they should look like and set about drawing the grid on my computer. I sized it to fit the number stamps and luckily it was just the right size to fit on an A5 card.
Nigel made me smile when he was showing it on TV. He came over all nostalgic as apparently he used to be a presenter on a bingo channel. I bet he was a laugh on that!
