Once upon a time, I didn't know anything about DIY and home improvement projects, but I'm slowly figuring out ways to make things easier. Here are some helpful things I've learned along the way.
Always spray paint outside - trust me, you'll want the ventilation.
If you wear glasses like me, take them off or make sure you have appropriate eye protection before you start. Glasses are expensive. You don't want to mess them up with paint splotches!
Once you're outside, make sure to set up away from things like vehicles - specifically your husbands new car...don't ask me how I know that.
I do most of my work outside while my son rides his bike and plays in the front yard - if he's outside, so am I. It can be hard to manage a project while trying to meet your child's needs, but it should go without saying that the child comes first.
That being said, it might be helpful to consider setting up a "safe zone" for your work. Find someplace that is out of reach for curious little fingers and not likely to be crashed into or run over by a ride-on fire truck.
This is a more regional tip geared more toward people in the South, but it's important for everyone to remember: If you're working outside in the sun, make sure you are properly hydrated and protected from the sun. I have very fair skin so a hat, sunglasses, and SPF 50+ are "must-haves" for me during the summertime.
