ATTENTION PLEASE READ. These are completely CHILD SAFE. We can customize these cordless spring loaded roller shades up to an 1/8th of an inch. Default is an OUTSIDE the window frame mount. After ordering we will reach out to see if you need an INSIDE the window frame mount and more precise measurements. For an inside mount, just give us the exact measurements of the opening rounding down to the nearest 1/8th and we will take any deduction needed to fit that space. We can customize any size from 12W x 12H to 94W X 96H. For an OUTSIDE the window frame mount we take no deductions. Our Sheer Roller Shades blend the versatility of a roller shade and the sleek look of a sheer shade. These shade are created with two layers of fabric - each paneled with solid and sheer fabrics. By positioning the fabrics together, you will achieve the traditional look of horizontal blinds. This allows you to see outside and allow in natural sunlight. When you wish to block light and increase your privacy, simply rotate the blind so that the solid fabrics fill in the shade, closing up all gaps.
