iPad 2 Cozy (or Book Cozy)

 You need:
  • approx. 100g sock yarn (or a small stack of scraps)
  • 3.50 mm (E) hook
  • one button 
Note: this pattern uses American terms, the British terms are in [brackets].

This cozy snugly fits an iPad 2, the dimensions of which are 9.5 inches (24.12 cm) x 7.31 inches (18.57 cm). Sock yarn is stretchy and I wanted a snugly-fitting cover, so it's slightly smaller than the device itself.

A note about gauge
Gauge. Ugh. What an odious way to begin a pattern. Sadly, it's unavoidable at this point, so let's just get through it as quickly as we can.

This cozy is basically a 12" (30.5 cm) x 12" (30.5 cm) square, made of smaller squares that are 2 inches (5 cm) in diameter. Each square must be 2 in / 5 cm across: I manage this by doing seven rounds with a 3.50 mm hook. If your square is too small after seven rounds, you may have to use a bigger hook - or stick with the same hook and add another round. If your square is too big, you might have to switch to a smaller hook - or stick with the same hook and do one round less. The main thing is, you have a 2 in/5 cm square at the end.
Okey dokey? Off we go.

How many squares do I need?
Brace yourself:


SQUARE
Round 1: Chain two, then do a SC [DC] in the same stitch below (this counts as your first SC [DC] here and throughout), then do 3 SC (DC) into the circle made by the first chain. *Chain 2 (to form a corner), 3 SC [DC] in the circle*. Repeat from * to ** twice more. You now have a very tiny square, made up of three SC [DC] on each side and two chains in each corner. Join with a slip stitch to the top of the first SC [DC], but be careful not to join in the top of the starting chain.


Round 2: Chain one, then do a SC [DC] in the same stitch below. Crochet 1 SC [DC] in next two stitches. *Crochet 1 SC [DC] + 2 chain + 1 SC [DC] in the corner chains of the previous row.  Crochet 1 SC [DC] in next three stitches.**
Repeat from * to ** twice more. Crochet 1 SC [DC] + 2 chain + 1 SC [DC] in the corner chains of the previous row. Join with a slip stitch to the top of the first SC [DC], but be careful not to join in the top of the starting chain. Note: your square should now have 5 SC [DC] on each side between the 2 chain that form the corner.

Round 3: Chain one, then do a SC [DC] in the same stitch below. Crochet 1 SC [DC] in next three stitches. *Crochet 1 SC [DC] + 2 chain + 1 SC [DC] in the corner chains of the previous row.  Crochet 1 SC [DC] in next five stitches.**
Repeat from * to ** twice more. Do 1 SC [DC] in next stitch. Join with a slip stitch to the top of the first SC [DC].  (7 SC [DC] on each side between the 2 chain that form the corner.)

Round 4: Chain one, then do a SC [DC] in the same stitch below. Crochet 1 SC [DC] in next five stitches. *Crochet 1 SC [DC] + 2 chain + 1 SC [DC] in the corner chains of the previous row.  Crochet 1 SC [DC] in next seven stitches.**
Repeat from * to ** twice more. Do 1 SC [DC] in next 2 stitches. Join with a slip stitch to the top of the first SC [DC].  (9 SC [DC] on each side between the 2 chain that form the corner.)

Round 5: Chain one, then do a SC [DC] in the same stitch below. Crochet 1 SC [DC] in next six stitches. *Crochet 1 SC [DC] + 2 chain + 1 SC [DC] in the corner chains of the previous row.  Crochet 1 SC [DC] in next nine stitches.**
Repeat from * to ** twice more. Do 1 SC [DC] in next three stitches. Join with a slip stitch to the top of the first SC [DC].  (11 SC [DC] on each side between the 2 chain that form the corner.)

Round 6: Chain one, then do a SC [DC] in the same stitch below. Crochet 1 SC [DC] in next seven stitches. *Crochet 1 SC [DC] + 2 chain + 1 SC [DC] in the corner chains of the previous row.  Crochet 1 SC [DC] in next eleven stitches.**
Repeat from * to ** twice more. Do 1 SC [DC] in next four stitches. Join with a slip stitch to the top of the first SC [DC].  (13 SC [DC] on each side between the 2 chain that form the corner.) 

Round 7: Chain one, then do a SC [DC] in the same stitch below. Crochet 1 SC [DC] in next eight stitches. *Crochet 1 SC [DC] + 2 chain + 1 SC [DC] in the corner chains of the previous row.  Crochet 1 SC [DC] in next thirteen stitches.**
Repeat from * to ** twice more. Do 1 SC [DC] in next five stitches. Join with a slip stitch to the top of the first SC [DC].  (15 SC [DC] on each side between the 2 chain that form the corner.)

Leave a tail twice as long as the square (can be used to sew the squares together.)

THE WEIRD SHAPE
This is basically a triangle, with another triangle added on to look like a square with a bite taken out of it.


Round 1: Chain two, then do a SC [DC] in the same stitch below (this counts as your first SC [DC] here and throughout), then do 3 SC (DC) into this circle made by the first chain. Chain 2 (to form a corner), 3 SC [DC] in the circle. Turn.

Round 2: Chain one, then do 2 SC [DC] in the same stitch below. Crochet 1 SC [DC] in next two stitches. *Crochet 1 SC [DC] + 2 chain + 1 SC [DC] in the corner chains of the previous row.  Crochet 1 SC [DC] in next two stitches and then do 2 SC [DC] in the final stitch. Turn.

Round 3: Chain one, 2 SC [DC] in the same stitch below. Crochet 1 SC [DC] in next four stitches. *Crochet 1 SC [DC] + 2 chain + 1 SC [DC] in the corner chains of the previous row.  Crochet 1 SC [DC] in next four stitches and then do 2 SC [DC] in the final stitch. Turn.

Round 4: Chain one, 2 SC [DC] in the same stitch below. Crochet 1 SC [DC] in next six stitches. *Crochet 1 SC [DC] + 2 chain + 1 SC [DC] in the corner chains of the previous row.  Crochet 1 SC [DC] in next six stitches and then do 2 SC [DC] in the final stitch. Turn.

Round 5: Chain one, 2 SC [DC] in the same stitch below. Crochet 1 SC [DC] in next eight stitches. *Crochet 1 SC [DC] + 2 chain + 1 SC [DC] in the corner chains of the previous row.  Crochet 1 SC [DC] in next eight stitches and then do 2 SC [DC] in the final stitch. Turn.

Round 6: Chain one, 2 SC [DC] in the same stitch below. Crochet 1 SC [DC] in next ten stitches. Crochet 1 SC [DC] + 2 chain + 1 SC [DC] in the corner chains of the previous row.  Crochet 1 SC [DC] in next ten stitches and then do 2 SC [DC] in the final stitch. Turn. 

Round 7: Chain one, 2 SC [DC] in the same stitch below. Crochet 1 SC [DC] in next twelve stitches. *Crochet 1 SC [DC] + 2 chain + 1 SC [DC] in the corner chains of the previous row.  Crochet 1 SC [DC] in next twelve stitches and then do 2 SC [DC] in the final stitch. Turn. 

Now the tricky bit. It involves maths. (My husband helped me with this, so it's probably correct.) Count the stitches you have on one side. If your gauge matches mine, you should have 15 stitches. Use this formula to calculate the number of stitches next needed:
number of stitches on one side multiplied by the square root of two divided by two equals number of stitches
15 x 1.4 (= square root of two) / 2 = 10.5 (-> 11 stitches)

Crochet 11 SC [DC]. Turn.
Crochet 1 SC [DC] in next 9 stitches, crochet 2 SCtog [DCtog] in final two stitches. Turn.
Crochet 2 SCtog [DCtog] in first two stitches, crochet 1 SC [DC] in next 7 stitches. Turn.
Crochet 1 SC [DC] in next 5 stitches, crochet 2 SCtog [DCtog] in final two stitches. Turn.
Crochet 2 SCtog [DCtog] in first two stitches, crochet 1 SC [DC] in next 3 stitches. Turn.
Crochet 1 SC [DC], crochet 2 SCtog [DCtog] in final two stitches. Turn.
Crochet 2 SCtog [DCtog] in final two stitches. Turn.
Crochet 1 SC [DC] in last stitch. Chain 1, leave a long tail of yarn to sew together.

Assembly
Sew the motifs together like this:
 




Do one round of SC [DC] around the sewn square, then a second round of SC [DC], creating a little loop of chains at the tip that's big enough for your chosen button to pass through.
 
Cut yarn and weave in end. Fold the square into an envelope-shape. Sew the flaps together and add the button.

Great use of scrap yarn! And I'm certain the measurements could be adapted for other notebooks.

This is about the prettiest cozy for an I-Pad or book I have seen so far! Thank you for sharing.
