Here are some good tips: https://www.canvastly.com/pages/tips-and-tricks

From the site: "Just like clothing, canvases are made from cotton, linen or polyester and can be ironed. You need to be careful not to set the iron on a high heat though – keep it on a mid-range heat setting. You should lay your canvas face down onto a thick towel and mist the back of the canvas lightly with water from a fine spray bottle. You just need to dampen the fabric rather than soak it. Gently iron over the surface, keeping the iron moving, and your canvas will be wrinkle-free within seconds."

normally when one says "stretch a painting canvas" it means over a wooden frame meant to hold the canvas. What came in your kit? Are there wood pieces?

No, just the wrinkled canvas with the printed picture on one side with the numbers that correspond with the little bottles of paint. Four brushes and a picture of what the finished picture should look like. That's it. No instructions, no wood and the brushes are very cheap. I'm no artist but I can tell I need better brushes and some help with getting the canvas ready to paint.

Hi KC, you can dry iron it.

1. Put a clean dry towel on the ironing board
2. Place the canvas face down
3. Place a thin piece of cloth on the inverted canvas
4. Set the iron to a high temperature
5. Turn off the steam, if you have that option
6. Start ironing across the canvas
7. Avoid lingering too long in the same spot
