If you want to recreate this by knitting, I agree the pattern may be simple, but appropriate yarn and yarn/needle ratio really is key.
May I suggest that once you have selected one or more yarns you like at the store, buying one small ball of each. Go home and make lots of little 10cm X 10cm samples (you can do 10 stitches / 20 rows). It goes fast, it'll get your hand back at it so you practice maintaining even yarn tension and avoid uneven fabric. One evening in front of the TV or radio or movie = lots of little samples.
Try the yarn using different needle sizes. For the kicks. Also, try different stitches to see the effect and determine which stitch would recreate the type of fabric/texture you are after. Don't mix too many stitches in one single sample, you won't be able to imagine and feel the effect on a larger scale. Try knitting two yarns together. Try thick yarn with smaller needles, thinner yarns with wider needles. Sometimes the most simple stitches have the best effect, but remember, the stitch must match the yarn. Some furry natural types almost require simple purl stitches all the way. I found rice stitch to yield most sturdiness if used with slightly smaller needles. Experiment!
Then, when you have the winner, it is like a secret magic formula. The sky is your limit.
