5 1/2 " X 6 1/2" for the outside
5 1/2 " X 7 1/2" for the inside
Keep in mind that once completed, a strip of the inside fabric will make the contrasting opening. (See the purple strip in the middle of the tiger print?)
Line up one 5 1/2" end where the fabrics are even.
Sew the raw ends with a 1/4" seam this time. Then just round the corners a little by stitching across. This will prevent the pointy ears on the corners. Trim the tip of the corners off, being careful not to cut your stitches.
Insert a personal pack of Kleenex or Puffs tissue. If using Puffs I carefully cut the top of the pack down the center. Puffs has the opening on one end where Kleenex has the opening in the center.
