Entrelac is build on the technique of half-crocheting. That’s why there are no traditional edge loops here. They are replaced by the edge loops we have as a result of crocheting rhombuses. Since an article crocheted according to this technique consists of rhombuses a side of it will serve as a pattern.
For example, this is what we’ll have:
The last row (the top of a rhombus): 3 last loops together.
Then, we need to go down from the top:
10 loops+10 loops+1 loop+10 loops. This is the way we form a new square rhombus. And start everything once again!
You may crochet in circles if you are making a skirt, a top, a sweater or anything that doesn’t have a zip fastener. In other words, you simply connect the last squares of the 1st row together and go on crocheting in circles.
