Assembling Tubey, part Deux

[continued...]

Now, match up the short ends of Tubey's top, sides, and bottom where the corners will be. Sew the corners like you did the long seam - very close to the edge.
















Here's Tubey with his corners done: He should rather resemble a box with no lid.

Now for the hard part: the back panel. First, line up the top edge of the back, with the back edge of the top. Pin, and sew.

Don't catch Tubey's antennae in his back seam, like I did here. *blush* Be similarly careful with the back and his right side, because of his tail!
