Barbara,
If you use your laser machine to create masks for flat items, your learning curve won't be too steep.
Learning how to manipulate artwork for application to curved surfaces, especially those with compound curves, will present a steeper learning curve.
For the easier applications, if you can spary a water hose on a sidewalk, you can sandcarve. :-)
