What Will You Make?
We will create a crochet bracelet for our micro:bit communicator. (https://youtu.be/weXGG8nBNjY) From our wrist we can send, receive and translate the Morse code.
What Will You Learn?
You will learn a Tunisian crochet style to create the bracelet of our spy communicator.
Grab your materials...let's get making!
Step 1
We will start with a slipknot, we will make 9 chains this will be the thickness of our bracelet.
Step 2
Now we are going to do something similar to the half stitch or half single crochet, we take our hook passing it through the second chain from the hook now we put our yarn on it and we take it out, we will have two lines on it, now place on the hook the yarn and pass it through one of these lines, you should keep two lines on your hook, repeat this step until you reach the end.
Step 3
You should have the same amount of chains as you did at the beginning, on your hook, now you will take the short end and pull it through all the chains, then carefully, you will take the chains back on your hook. Take the other end, put it under the hook and pass it through all the chains.
Step 4
This step is very interesting, among the chains you will see 3 threads the first, with the help of our crochet hook, we will take it around our piece, leaving the same number of chains from the beginning. Now we will place the end under the crochet hook, and we will pass it through all our chains.
Step 5
Repeat the last step around the following rounds, until reaching the thickness of our wrist. Tip: Add a few extra rounds when it’s the thickness of your wrist to make it easy to put on.
Step 6
Now we are going to cut off our yarn end, remember to leave some yarn as we will use it later. Then place both ends on the 3D base.
Step 7
To close our piece, with the help of our crochet hook we will repeat our step 4, having all our chains on the hook, we will place the end on our yarn needle and we will cross the first chain of the opposite end to our crochet hook, then the first chain inside this, and so we will advance with the rest of the chains.
Step 8
Finally tie a knot and cut off both ends.
