Abbreviations (US terms)

ch
chain
sc
single crochet
ss
slip stitch
BS
bobble stitch. (yarn over, pull up loop, yarn over, pull through first two loops on hook)4 times in the same stitch, yarn over, pull loop through all loops on hook. Normally, the bobble stitch ‘puffs’ to the back. However, mine tend to puff to the front. It doesn’t really matter, as long as you’re consistent (and use the puffy side as the outside of your cover).

Repeat formats

  • […]Indicates the amount of stitches at the end of a row or round.
  • (…) in same st/spIndicates that all instructions between brackets are worked in the same stitch or space.

Crochet pattern

With Colour A, ch25. You will be working on both sides of the beginning chain.

Crochet rounds
Round 1 (RS)Starting in second ch from hook, 23sc, 4sc in last ch, 22sc (on the other side of the chain), 2sc in last ch, join with ss in first sc.[52 sc]
Round 2 (RS)Ch1, 1sc in same stitch, BS in next st, (1sc, BS) 25 times, join last BS with ss in first sc (important here is to pull the sc really, really tight! They make your BS puff more).[26 BS, 26 sc]
Round 3 (RS)Ch1, 1sc in same stitch, 51sc, join with ss in first sc. Cut yarn.[52 sc]

Repeat Rounds 2-3 for every colour in alphabetical sequence. I’ve repeated all the colours, and red, orange, yellow, bright green, dark green and petrol/turquoise twice. Weave in all your ends, and you’re done!

I recommend fitting your sleeve after Round 5, to make sure your width is. It’s ok if you have to stretch it a little, this makes sure your tablet is nice and snuggly in its cover. You rather want it to be a little bit stretched instead of too loose!

Adjusting measurements

It’s easy to adapt this pattern for another size of tablet. As these kind of sleeves are pretty stretch, thickness of your tablet is not really an issue. Heightwise, you can just add or discard a couple of colours/rows. The width of the sleeve (i.e. the number of stitches in a row) can be easily changed by adding chains in steps of two to your beginning ch. Because you’re crocheting in both sides of the begin chain, one extra chain equals 2 sc. Basically, when you end up with an even number of stitches in Round 1, you’re good to go!
