I have had this done for just that reason and I took the pattern to a glass shop. They cut the pieces precisely, and smoothed the edges. I asked for 1/4" plexiglass so I could use it with my rotary cutter. The price was very reasonable. Seems like there were 4 or 5 pieces and the bill was around $20. That was in 2013. Depending on your location, the prices would vary - I would tell them the limit I was willing to pay so they would be able to determine whether they were interested in the project since your shapes might be more intricate and take more time to cut. As quilters we understand that some projects like 4 patch are fast, and some like applique are slow, so is cutting plexiglass. Not just the price of materials. Good luck
