Since I am a big fan of the ripple stitch pattern I want to share with you this how-to , so you can also make a nice ripple pattern scarf, blanket or whatever. It's very easy! (and addictive...)
I'm working on a scarf myself (see above) and I have to hurry a bit because it's getting colder outside. So actually I don't have time for this tutorial, but here it is anyway :)
1. Crochet a foundation chain. It should be in multiples of 16 chains plus an extra two for the turning. It's best to use a bigger hook for the chain, one size bigger is okay, because otherwise your treble crochet stitch (this is UK treble / US dc) won't fit in the loops. For my example I crocheted 34 chains (2x16+2).
2. When you've got the right number of stitches, make a treble crochet stitch (this is UK treble / US dc) in the 3th chain from the hook. Use the smaller hook from now on! Now crochet 6 treble crochet stitches.
3. Now we're going to crochet our first mountain. Work 3 tr's into the next chain. There it is already :) Again crochet 6 tr's.
4. Now it's time for the first valley with a standard decrease stitch. This is where you work 3 incomplete tr's, joining them into 1 stitch at the finish.
5. From now you keep crocheting 6 tr's, a mountain, 6 tr's, a valley, 6 crochets, a mountain etc etc. You should have 2 chains left at the end of your foundation chain. Use again the standard decrease stitch. If you want to change colours, this is the time! Insert a new colour in the last stitch of the decrease stitch.
6. Chain 2 and turn your work. Skip the first chain and then crochet 7 tr's.
7. From now on crochet a valley above a valley and a mountain above a mountain.
Note: In this tutorial I don't explain all the stitches that are used. You can find those all over the internet. If you have any questions: please comment!
