Easy. Straightforward. Best if knit from Kekistani fibers.
Step 1: The Body
knitting needles, US 11/8mm
3 strands of yarn
Using shades of green gives a nice effect
Step 2: Ready, Set, Ribbit!
1. Cast on 28 stitches
2. Purl, knit, knit, purl, purl..........knit, knit, purl
3. Create 4 rows of ribbing, then knit stockinette stitch until your piece is 7-8 inches
Step 3: Eyelids
Switch all yarns to lightest green
Knit 6 rows
Step 4: Eyeballs
Switch all yarns to cream.
Knit 10 rows
Step 5: Face
Replace cream with green yarn.
Knit 12 or 14 rows.
For Froggy lips, replace green yarn with red.
Knit 3 or 4 rows of ribbing, then cast off.
Step 6: Vision
Using a dark color, sew irises on in upside-down "v" pattern, laying over knits.
Be sure to center and place everything symmetrically, if that's what you want.
Using cream, add sparkles to pupils, to take away the zombie look.
Step 7: Sew Hat
Fold rectangle in half, right sides together.
Starting at bottom, stitch sides together using a ladder stitch. Round off corners to give Froggy's eyes a nice curve.
