Chris: Good Morning. I spoke with Blind Appeal owner. Bay windows are a bit difficult as each set of bay windows are completely different and also a challenge. Typically the best option is for cellular shades since they have a small profile and can typically fit in a bay window without butting up against each other in the corners. Please see Blind Appeal's video on Cellular/Honeycomb shades, which might be helpful for you with those bay windows. Thanks for your question!
