Need some help with how to make it look nicer/more fun please! Any suggestions are welcome ?

Use a chalk pen, they work great

Would use fun pictures around the frame from birth till now! ?

Chalk pen for sure

Are you doing a certain theme? You could do cutouts and put them along the frame?

All the bright colours are chalk pens :) going to be writing in the rest in them when I've 100% chosen what to put in them

The pictures sound like a great idea! And no theme (no party) but because of his name we like to have whale stuff ?

Kudos to you for making your own!! I ordered one off of Etsy, and I love it, but it's not the same as saying I made it myself!!

Im going to post a picture of the one I made because I cant explain the dotted line thing without it sounding weird
