Fabric yarn. I can't give you exact yardage, but I used approximately half of what I got from the duvet cover, which was 135 x 200 cm, cut into one long continuous strip about 2 cm (4/5 inch) wide.
Big crochet hook. I used a 10mm for this project, but would have used my 12mm hook if I had been able to find it.
A smaller crochet hook, e.g. a 5mm. For finishing.
slst - slip stitch
ch - chain stitch
sc - single crochet (I'm using American terms)
dc - double crochet
Beginning round A: Make a magic ring and make six sc in around it. Pull to close.
Beginning round B: Make 6 ch and connect with a slst into the first ch.
1. Make 2 sc in each ch around (12 sc).
2. Make 2 sc in the first sc, 1 sc in the second sc, repeat around (18 sc).
3. Make 2 sc in the fist sc, 1 in the next 2 sc, repeat all around (24 sc)
You now have the beginnings of a bottom for your fabric basket. To adjust the size:
Depending on how large you want the basket to be, continue by increasing the number of single sc's between sc by one for each round you make so that, e.g. you make 2 sc and then 3 x 1 sc in the fourth round, 2 sc and then 4 x 1 sc in the fifth round, and so on. This particular basket is made with a total of 7 rounds for the bottom.
You can stop after this, and you will have a trivet, or you can continue increasing the number of single sc's between the sc's with two sc's until you have a rug.
To make the sides:
Continuing in a spiral, stop increasing and work one sc in each sc until the sides are high enough for your taste. If you want the delimitation between the bottom and the sides to be less rounded and the basket more cylindrical in shape, work the first round of sc's in the back loops only.
To make the scallops:
Chain 3, make 4 dc in same sc. Connect with slst in 3rd sc from the sc you are working in. Repeat around. If it looks like you will have a gap of one or two sc at the end, adjust by connecting the last one or two scallops one sc less or one sc farther from the sc you are working on.
You can also make a handle:
Make 3 ch in the last sc worked, dc in the next sc, turn and continue this way until the handle is long enough. Then connect to the opposite side with 2 slst.
Use as you please. If you chose the fabric sensibly, you will be able to throw the basket in the washing machine if it gets dirty. I'm sure I don't have to stress that this is important if you plan to keep food in it, especially food that can leave crumbs trapped in between the knots (e.g. bread) or leak stains in the the fabric (e.g. fruit).
