Production of vein bookmarks

1. Pick some leaves with clear and tough veins, such as mulberry leaves and osmanthus leaves.

2. Weigh 2.5 grams of sodium carbonate and 3.5 grams (or 3 grams) of sodium hydroxide, put them in a beaker, inject 100 ml of water, and put them on the fire to boil.

3. Throw the leaves in and let them all soak in the solution. Continue to heat for 6~8 minutes, and gently stir with a glass rod from time to time to separate the leaves and heat evenly. When the leaves are corroded by drugs, the soft parts are easily removed, leaving veins.

4. Take out the boiled leaves with tweezers and put them in a glass filled with clear water.

5. Take the clean leaves out of the clear water, lay them flat on the palm of your left hand, carefully wipe off the soft parts of the leaves with the index finger of your right hand in running water to reveal clear veins, and then stick them on the glass to dry.

6. Before the veins are wet, paint them with watercolor paint (or dip them in colored ink for dyeing). After drying, put it in a book and flatten it. Then tie a colorful ribbon on the petiole to make a beautiful bookmark.

Second, how to make bookmarks is the most common.

Veins bookmarks is a bookmark made by selecting beautiful leaves, removing mesophyll by chemical treatment and keeping the whole vein.

Making vein bookmarks can be used as a way for laid-off workers and wealthy rural laborers to make money. Manufacturing method: 1, select the blade.

Choose leaves with thick veins. Generally evergreen woody plants are better.

Such as osmanthus leaves, heather leaves, papaya leaves, eucalyptus branches and leaves, tea and so on. Choose leaves in late summer or autumn when they are fully mature and begin to age.

2. Boil the leaves with lye. Configuration of lye: calculated by 1 liter of water, sodium carbonate (sodium bicarbonate) 70g, sodium hydroxide 50g (the above two drugs and chemicals are available in stores), or lime water is used instead of lye. Boil the prepared lye in an enamel cup or casserole, and then boil it in a proper amount of washed leaves. Gently stir the leaves with chopsticks to prevent overlapping and make them evenly heated.

Cook for about 5 minutes. After the leaves turn black, take a leaf and put it in a plastic basin filled with clear water. Check the corrosion and easy peeling of mesophyll. If it is easy to separate, take all the leaves out and put them in a plastic basin filled with clear water, and then separate the mesophyll and veins one by one.

3. Remove the mesophyll. Put the cooked leaves on the palm of your hand or a glass plate, gently rub them with the smooth part of the old toothbrush handle to wipe off the corroded mesophyll, then rinse them under the tap and continue rubbing until the mesophyll is completely removed.

4. Bleach blood vessels. Bleaching the scrubbed veins in bleaching powder solution, taking them out, washing them with clear water, putting them into old books and newspapers, absorbing moisture, and taking them out as veins bookmarks.

5. Dye, draw and write. Dye your favorite color with red and blue ink or other dyes, or draw and write on it, and finally tie it with silk thread.

Third, how to make a simple bookmark program

Materials: various colors of cardboard, colored pens, pencils, scissors, rubber, film.

0 10203040506 operation method 0 1 find the cardboard with your favorite color, which determines the overall style of the bookmark, and then draw the length of the bookmark on the paper.

If there is no hand-drawn foundation, you can also write a motto of self-encouragement.

When you finish painting, you should draw with a marker. You can look at your personal preferences or find a template of relevant materials to draw. Find some plastic film or plastic wrap, or cut it out of plastic bags.

Cover the bookmark with a film, and this personalized bookmark made by hand DIY will come out of your hand. If you want to be more convenient, you can make a small hole in the bookmark head and tie a line.

Such a personalized bookmark of your own style is completed! .

Fourth, how do primary school students make bookmarks

Ordinary bookmark

Use art paper first? Be hard? Cut out a character to the bottom? And write some famous sayings yourself? Finish it and decorate it? Stick three-dimensional double-sided tape first? Then cut some patterns and paste them, and add some sticky paper. Can vein bookmarks be dried first? Don't pick too big leaves? Stuffed in a thick book or dictionary? Double-sided absorbent paper? Change absorbent paper often? Until the handle is brittle? And then go to the photo shoot and ask for a plastic? It's also very nice. Of course, this is just a simple method, okay? Not as delicate and beautiful as it says? For reference only. ? How many more slices will you make when you make them? Maybe it won't succeed at once for various reasons? Remember to handle it carefully.

Method for make cardboard bookmark

Prepared materials? Cardboard, glue, two beautiful pieces of paper with cartoon patterns, scissors, etc.

Steps? 1. Cut the cardboard into the shape you like. Leaves, flowers, etc?

2. Cut one of them into the same shape as cardboard with scissors? Glue the book to the front.

3. Write the famous aphorisms of reading on the front? And draw your favorite pattern in the blank.

4. Cut another piece of paper into the same pattern.

Sixth, the method of making bookmarks

Pick up the leaves. 2. Cook the leaves and alkali together for a while. 3. After the leaves are cooked, take them out and gently scrape off the green on the surface with a fine-haired toothbrush. There is only one transparent leaf left. Finally, put them in a ventilated place (not sunny enough) to dry. Let's briefly introduce the structure of leaves: the surface of leaves is surrounded by a layer of epidermal cells, which has the function of protecting leaves.

Inside the epidermis are some mesophyll tissues containing green leaves, which can be used for photosynthesis. Through mesophyll tissue are veins composed of transport tissue and mechanical tissue.

Veins bookmarks is made of veins only by removing epidermis and mesophyll tissue. On the bookmark, you can see that a thick vein in the middle is called the main vein, and many smaller branches on the main vein are called lateral veins; On the lateral vein, there are smaller branches called veinlets.

In this way, the whole venous system is finally connected into a network structure. Dye the mesh in various colors, tie a ribbon and make a beautiful mesh bookmark.

Now let's talk about the whole process of making veins bookmarks: leaves from cortex are usually used, such as leaves from osmanthus trees and leaves from beech plants. The picked leaves should be the right size, not incomplete, older and not too tender.

After picking leaves, put them into a beaker (as shown in Figure 1), add 10~ 15% sodium hydroxide aqueous solution (until the leaves are submerged), heat and boil 10~ 15 minutes (as shown in Figure 2), take them out and spread them on plastic gauze. After the above treatment, the epidermis and mesophyll tissue of the leaves are dispersed and washed away by tap water, leaving reticular veins.

After washing the veins, pick them up and spread them on absorbent paper, press them dry and flatten them, and then dye them in the dye vat. A variety of dyes can be used for dyeing (as shown in Figure 4).

Red ink and blue ink are also good. Dye 1~2 hours, take it out, spread it flat on absorbent paper, flatten it and dry it.

After taking it out, tie a ribbon at the bottom of the coarse texture to make a texture bookmark.
