Crochet: Looks knit book sleeve

As I'm a bibliophile, aside from bookmarks, I should be making book sleeves too right?!!! So here's a pattern I've discovered from the web, very easy to make with just chain and half double crochets...

And this is the outcome! Though I prefer yarns from Nona as the quality is much better but since I couldn't find shops selling Nona yarns thus have to settle with Minlon. Thankfully, am loving the mixed colour yarn from Minlon so far and it's not as coarse as the single coloured ones!

What I've used:

• 100% acrylic yarn
• button
• hair tie
