Here are pictures of the projects from days 5-9:

For my final project I chose to do a combination of the circles and sparks!

Incidentally, when I did day 6, I didn’t have any straws in the house, so I improvised with a biro lid with its vented safety cap!!!! But the activity was so much fun - and I can see me using a version of this for greetings cards in future - that I have now acquired some paper straws to use going forward
