Step: 1. First, print the template on the back of the paper, and cut it along the solid line with scissors to prepare 20 circular plates; 2. The back of the paper (that is, the patterned side) faces upwards, and the edges except the triangle are folded backwards, and all 20 sheets are folded into triangles; 3. The ball consists of three parts: the upper part, the middle part and the bottom part. The upper part and the lower part are made in the same way. Take five templates and put the vertices of the triangle upward. Glue the folded parts on both sides of adjacent vertices together, and finally glue the two ends together to form a hemisphere as shown on the right. Make two hemispheres, the upper part and the lower part; 4. Making the middle section: the vertices of the triangle are alternately placed up and down, the folded parts on both sides of adjacent vertices are glued together, and finally the head and tail are glued together to form a ring, and the middle section is finished; 5. Finally, the upper part, the middle part and the bottom are glued together to make a ball.

2. How to arrange flowers and colorful willows on the wedding road to look good?

Matters needing attention in keeping roses fresh by inserting water.

1 Use a sharp knife to cut obliquely, and cut off the end of the stem by about 2 cm to make the incision smooth and increase the water absorption area.

Wood can be cut from the end of the epidermis or cross-shaped. If it is too thick, the end can be broken to increase the water absorption area.

Use clean water and vases.

4. Warm water was used at the initial stage of treatment.

5 Add preservatives.

6 Remove the branches and leaves under the liquid surface.

If the flowers wither, you can wrap them in wet newspaper for 2-3 hours.

Avoid high temperature and dry environment, especially in direct sunlight.

Flowers should not be placed with apples, pineapples, bananas and other fruits.

Secondary water treatment method:

1 soaking method:

Roses are easily weakened by high temperature, so they can be soaked in water to increase the water absorption area.

2 water injection method:

Rose stems are hollow and easy to lose water. You can use a water gun or syringe to fill the pedicel and then plug it with cotton, which can prolong the flowering period.

3 reverse water method:

Turn the flowers upside down, water them in the opposite direction with a watering can, and the water flows into the stems and leaves in the opposite direction to increase the water absorption area.

3. Chemical treatment:

1 dressing (such as salt, alcohol, alum, mint, oil, etc. ) to the incision can inhibit the growth of bacteria and prolong the life of the flower material.

Adding acetic acid, citric acid or bleach to water can inhibit the growth of bacteria, but the concentration should not be too high.

Four heat treatment methods:

1 hot water method:

Wrap flowers in newspaper and soak them in hot water for about 30 seconds, which can kill some bacteria and prolong the flowering period.

2 cauterization:

Some flowers will secrete mucus to block the incision, resulting in poor water absorption. You can burn the incision until it turns black.

Secrete mucus.

In addition:

Extending the life of flower arrangement is divided into two steps, that is, flower pretreatment before flower arrangement and reasonable maintenance after insertion. Let's talk about the pretreatment method of flowers before flower arrangement:

Water cutting method: cut the flower branches in water, so that the incision is not in contact with air when it leaves the mother body; You can also immerse the cut flower branches in water and cut another section in the water to prevent air from entering. This method is suitable for all flower branches except those with emulsion, but it should be noted that the flower head must be above the water. Heat treatment method: soaking and scalding method and burn method were used respectively. Scalding method is to cut off the ends of flower branches of plants and flowers, soak them in hot water at 80℃ for about 65438 0 minutes, and then take them out and insert them into a bottle, which can play the role of blocking the incision and prevent the liquid in the flower branches from overflowing, thus prolonging the flowering period. The burning method is to burn the ends of branches of woody flowers on a flame for 2-3 minutes, then cut off some burned branches, soak them in alcohol for 1 minute, take them out, rinse them with clear water, and insert them into a bottle. This can not only prevent the conductive tissue of the branches from blocking, but also prevent the branches from being infected by bacteria. In this way, flowers can get water continuously. Hydrangea, clove, woody, peony, rose, chrysanthemum, ivory red, etc. It can be treated in this way. Physical treatment methods of incision: first, cut the incision into an inclined plane when cutting the flower branch to increase the water absorption surface of the flower branch; Secondly, some branches with brittle branches are directly broken by hand to enlarge the incision, so that the branched catheter is not damaged; The third is to split the longitudinal surface of the incision into several parts, embed small stones and open the incision. Fourth, gently crush the cut flower branches at the base for about 3 cm to increase the water absorption area and prolong the life of flower arrangement. Generally, plants and flowers should adopt oblique incision, and woody flowers should adopt branch folding and pressing method. Acid and alkali treatment: apply any one of acetic acid, dilute hydrochloric acid, boric acid and salt to the incision. Ways to increase nutrition: sugar, vitamins, growth hormone, medical painkillers, etc. It can be added to the water in the flower arrangement container, which can prolong the fresh-keeping time of flowers and prolong the flowering period, but it must be appropriate. Maintenance of fresh cut flowers After pretreatment, fresh cut flowers can be arranged, but it must be noted that the water in the container should be clean, the water depth should be above the incision, and the water surface should have the greatest contact with the air. The depth of the vegetable container should be soaked at the height of flower arrangement to ensure that the incision of the flower material can absorb water in time; The water depth of the bottle container should be at the widest part of the bottle, because the water surface here has the greatest contact with the air, which is conducive to ventilation, smooth breathing of flowers and reduce bacterial infection. The following are the main points of fresh cut flowers: rational water use: clean river water, well water and pond water should be used when arranging flowers. When the water quality is turbid, it must be clarified before use. If tap water is used, it should be put in a tank (barrel) for one day and one night before use. Change water frequently: change water every 1-2 days in summer and every 2-3 days in autumn and winter (to prevent bottle water from deteriorating, a small amount of preservatives such as salt can be put). When changing water, remove the remaining flowers and leaves, cut off the branches properly, change the incision and spray water on the flowers. Reasonable placement of flowers: Avoid direct sunlight in summer and stay away from heating or stoves in winter, otherwise it will accelerate the respiration of flower branches and the evaporation of water, which will easily cause flowers to wither. In addition, we must be careful not to put the flower arrangement near the ripe fruit, because the fruit will release ethylene, which is a harmful gas that has a special effect on cut flowers and will lead to the premature withering of cut flowers. First of all, when you buy it, you can cut the flower branches into inclined planes, which is to make the flowers absorb water better. Secondly, you can put some crystals beside it, because the magnetic field of crystals can prolong the flowering period. Change the water frequently, cut off the lower end of the branch 1 cm, cut it into crosses and divide it into four petals. Choose fresh flowers to avoid direct sunlight and excessive ventilation.
