We understand getting the correct size insert for your sham can be difficult but don't worry we've got you covered.

Step 1: Measure sham along the seam from corner to corner, please watch video below

Step 2: Using the yellow chart determine the insert you need

Step 3: Select quantity of pillows to replace

Step 4: Be sure to include your Amazon order number and your sham size and insert size you need when adding an item to the cart.

Step 5:  Do not return the original pillow(s) to Amazon.  They are considered used bedding and will be destroyed.  Please consider donating the pillow(s) to a local charity.


That is it! You are done. We will get your replacement pillow(s) out within 3 business days.
