Get it:

Four patterns of fabric cut in the following sizes:
4 2" squares (arms)
2 2.75 x 3" rectangles (head)
2 4" squares (body)
1 4x5 rectangle (pocket)
scrap of felt or linen for face
stuffing
embroidery thread for mouth

Do it:

Sew face on one side of head piece. Zigzag works great for linen, but felt can be sewn in a straight stitch or even by hand. Center head pieces on body pieces, right sides together and sew.

Sew arms together on three sides, right sides facing each other. Turn, press and stuff lightly.

Iron pocket in half, making it 2.5" tall, 4" wide. Pin on body piece that has face.

Pin on arms, raw ends matching onto sides of the body (arms are pointing in) about 1/2" down on body piece. They will overlap with the pocket a bit, that's okay.

Finish your robot sandwich by placing back body piece, face down on top. pin all around. Remove unnecessary pins (don't want them stuck in your pillow...ouch). Sew all around edge, leaving a hole for turning. Remember the hole needs to be big enough to get the arms through. Check before you turn and stuff to make sure you have everything sewn in there all tidy. There's nothing more frustrating that turning and getting halfway stuffed before realizing you have a popped seam. argh.

Stuff and stitch opening closed. Add buttons for eyes and embroider mouth, going in under the face to hide the knot. Beep! Boop! You're done! Speaking of robots, we went and saw Wall-E yesterday. Turned me off of Jamba Juice forever.

Have a great weekend!
