It's actually pretty cheap to do. $6.99 on Amazon https://www.amazon.com/HGLARX-Window-Non-Adhesive-Film-30x200CM/dp/B07S7RWVW8/ref=sr_1_108?crid=1BSYRYZRRYHCC&keywords=window+privacy+film&qid=1567885673&s=gateway&sprefix=window+pri%2Caps%2C168&sr=8-108 is the one I got off of amazon. Plus I have some in my kitchen window for morning rainbows. I just used an exacto knife to trim it. But scissors can do the same.
