It's no secret that leaves are different. For each specific case when a flower is created, a special leaf is useful. Crocheting them is simple. The main thing is to know the circuit diagram.
Classic oval leaf
First, draw a chain of so many loops so that it is equal to the total length. A leaf (crochet) will be tied on it. For example, let the number of loops be 13. An odd number is recommended due to the symmetry of the pattern.
Next, on two sides of this chain you need to tie a leaf (crochet). The scheme is symmetrical about the middle of the chain. In the second and third loop, make along the connecting column. The fourth loop requires a single crochet. In the fifth and sixth will be placed one column with a crochet. The next loop becomes the base of two double crochet posts. In the eighth loop (middle of the chain), connect two columns with three crochets. Then in the mirror order there are columns with a decrease in their length.
At the edge, tie the connecting column and go to the other side of the chain. Run a pattern symmetrical to the first half of the sheet.
Now it remains to make a vein in the center so that the leaf (crocheted) looks more like a real one. It is done with simple connecting posts with the thread picking up from under the product.
Shamrock
You need to start knitting such a leaf (crochet) with a chain of 12 air loops, which must be closed in a ring. In the first row, perform such columns: 2 single crochet, 2 double crochet, 4 double crochet, again 2 single crochet and another 2 single crochet. Close the circle.
Second row: at each vertex, make two double crochets. Close the circle and start likewise knitting the second petal. Then the third.
Thread a hook into the base of all three petals and pull a thread through them. Collect 15 loops on which to connect the connecting posts.
Leaf foot
The technology of how to crochet a leaf may be slightly different. And this is often found in knitwear for decoration.
Start with a chain of 11 loops. Through its entire length, tie the connecting posts. Perform a 3-loop climb. Again, make a row of connecting columns, leaving two columns of the previous row loose. Turn work.
An air loop and connecting posts to the end of the row, the latter to be made into an arch of air loops. Three air loops and one more connecting in the same arch. Run connecting posts on the other side of the leaf, again without tying two at the end of the row. The initial chain should be in the center and be the longest.
Continue the same knitting until the desired sheet size is obtained. At least there should be three such fillets. Otherwise, the leaf will be too small.
Heart Shamrock
Dial a chain of air loops, the length of which will be approximately 3 cm. It is necessary to tie the connecting posts on it. It will be a leaf stalk. Three hearts will be placed on it.
All work will go on the front side. Hearts will make a pattern (crochet), the leaves will be directed from the middle outward from the central circle. It needs to be made of 9 loops. Then tie with connecting posts.
Collect 8 loops from the circle, knit connecting posts on them. The next row will give the first half of one petal. It consists of: 1 connecting, 1 single crochet, 1 half-crochet, 1 double crochet, 1 double crochet, in the last loop of the chain tie a fan of three double crochets, 4 air and connecting to that loop, where knitted fan. Then repeat everything in reverse order to get the second half of the petal.
Similarly, knit the other two petals. Between themselves they should be connected by half columns.
Rowan leaf
It consists of nine identical petals to get a nice and symmetrical leaf (crochet). The scheme of each petal is formed from the following elements: connecting, single crochet, double crochet, double crochet, again double crochet, one more single crochet and connecting.
You need to start knitting with a chain of 12 loops. On the last 8, perform a petal, leaving one of the typed loops for lifting. Pick up 12 more loops. On them, tie another petal. Repeat two more times. It turned out four petals on the right side.
For the central petal, you will need to dial only 8 loops. Do the same with the 6th leaf petal. After it, on a chain of air loops, connect three connecting posts. Collect 8 loops and tie a petal. Repeat two more times.
The second, third, seventh and eighth petals can be made one loop longer and in the middle tie an additional column with two crochets. So the leaf will turn out closer to what is in nature.
Conclusion
To make the leaves light and airy, the yarn should be thin enough. In this case, it is better to take the hook as small as possible. And then the decoration of flowers with leaves will be elegant and spectacular.
