Please tell me how I can improve this segment of my writing thxs please!

A few months ago when i was walking down the street i saw the crosswalks where wet with paint and some people walking around with paintbrushes, so i decided to see what was going on. They told me that they were doing sidewalk paintings, so i asked if i could join in and they said i could but i would have to put down some tape first. Once that was done i picked out a color and just did what i wanted to my 2 panels of sidewalk. When we were done for the day i got a really cool coupon for a craft store in appleton. I had a great time making friends and painting things for all to enjoy!
