Hi @uksll,

Your current options might be a bit confusing for your customers. Could you please clarify which choices are available for your Pillows (e.g., color) and Pillowcase (e.g., shape, color)? Also, is there any connection between the Pillows and Pillowcases? Do you offer them as a set, as separate products, or both? Once I have this information, I can provide a more suitable solution.
