First sew your pillow fabric and velcro to the nap mat cover. Then place nap mat right sides together, insert blanket (making sure itâs inside the mat). Stitch around sides and top, leave your velcro end unstitched and a gap to stuff your pillow. Turn right side out. Stitch a line where your pillow and mat fabric meet.
Next, measure how big your mat board needs to be to fit inside your chosen frame. Take a larger sheet of board and trim it down using a plain cutting knife and ruler, making sure it's perfectly square (as in 90 degree corners)!! The quilter's rule can be handy for this. Doin' maths. On the back of your cut mat board, do some maths to figure out the position of the hole you're going to cut.
