This is an upgrade to a blanket you are ordering. It will upgrade your blanket to 4 inch squares which is smaller than the 5 inch squares that I use for my blankets.
Your blanket will have smaller squares which helps limit the movement of the pellets or glass beads.
Your blanket will probably be a little large because I will add a little extra in length and width to accommodate for the 4 inch squares.
30x50 blankets will be 32x52
40x65 blankets will be 40x68
50x80 blankets will be 52x80
Please ask me any questions that you have.
