I am a primitive

Doing so facilitates modification.

After the sketch is almost done, I will change to a thicker charcoal pencil, and trace it along the previously sketched place.

In this way, those places that were drawn wrong before will not look conspicuous.

Children who don't have rubber can't afford to be injured, so they can only use this method.

After sketching for about an hour, Han Chengcai put down the charcoal pencil in his hand.

Looking at the patterns on the paper, Han Cheng smiled with satisfaction.

With such a thing, the next trip will save a lot of effort, after all, this thing is a sharp weapon for traveling.

After looking at the blueprint in his hand for a while, the happy Han Cheng went to find Bai Xuemei with the blueprint in his hand.

Xiao Xing'er is now more than one year old, and compared to before, she is much easier to manage, at least she can walk slowly by herself, and she doesn't need to be hugged all the time.

Han Cheng came to the room where he lived, picked up Xiao Xing'er who had walked to the door of the room, kissed the little boy twice fiercely, and then used his fingers to scratch the little guy's armpit a few times through the armpit , making the little girl giggle with joy.

Amidst the little girl's laughter, Han Cheng carried her to the edge of the kang, handed the blueprint in his hand to the sitting there, and took the needle and thread to sew springs for Xiao Wandou and Xiao Xing'er. Bai Xuemei in clothes from time to time.

After Bai Xuemei took it, she unfolded it and saw that there was something like a leather bag in the tribe drawn on it.

Different from the leather bag, this bag drawn by brother Cheng on the paper is not cylindrical, but looks a bit like a half cylinder.

And on the half of the cylindrical plane, two wide belts are drawn, the style is very strange.

"Brother Cheng, what is this?"

After looking at it for a while, Bai Xuemei raised her head to look at Han Cheng who was having fun hugging Xiao Xing'er and asked.

"It's a backpack that can be used to pack things when you go out.

After loading things, you can carry them on your shoulders, and you don't need to use both hands to support them, so they can stick to your back and not fall off.

Because the weight is directly distributed on the two shoulders, the same weight is carried on the body with a backpack, which is much lighter than carrying it by hand or on the shoulder.

Moreover, with a backpack to carry things, both hands can be free.

The free hand can be used to hold weapons or do other things, which is very convenient.

After the beginning of spring, when I go south to find a new place suitable for the tribe to live in, I plan to let everyone who sets out carry such a backpack on their backs. "

Han Cheng explained to Bai Xuemei with a smile.

In the later generations, backpacks are simply a sharp tool for traveling, especially when hiking, travel bags are even more essential.

This trip after the beginning of spring is much more exciting than those hiking trips in later generations. After all, this is really primitive, the kind that is fake.

If these people who go out all carry a backpack on their backs, it will save a lot of energy, and it can also liberate everyone's hands, which is of great benefit.

It was precisely because of this that Han Cheng was so happy. After thinking about it, he would not do other things, but concentrate on drawing the pattern of the backpack first, and then come to find Bai Xuemei and ask her to make it.

Bai Xuemei's hands are very skillful, not only in weaving, but also among the top existences in the tribe, even in sewing and mending, she belongs to the top group in the entire Qingque tribe.

So there is no need to trouble other people in the tribe with such things.

After listening to Han Cheng's explanation, Bai Xuemei immediately paid attention.

Such a good thing, no matter what you say, you have to make it!

After all, this is a matter related to the safety of those who are going out.

Immediately began to ask Han Cheng some more things about the backpack.

Han Cheng also explained and described Bai Xuemei based on the appearance of the backpack seen by later generations.

After doing this for a while, Bai Xuemei, who had roughly figured out what was going on, started to find materials and started to make this backpack.

Han Cheng was on the sidelines, not saying a word or two to give pointers.

There is no way, although he is not a tailor, but he can't hold up to many backpacks he has seen.

The materials used by Bai Xuemei to make backpacks are very luxurious, and the materials used directly are leather.

This is genuine leather, not faux leather or anything like that.

It is also very simple and rough when cutting.

First cut out a semicircle with a diameter of forty as the base, and then cut out a rectangular animal skin with a width of 1.1 centimeters and a length of about [-] meters.

Then first sew the hide into a cylinder, and find two sticks one centimeter thick and [-] centimeters long and put them inside the hide cylinder.

The distance between the two sticks is 39 cm, one end of the stick is flush with the other end of the hide, and then the two sticks are sewn there.

Of course, it is not the cylindrical sewing, but the animal skin at the distance of 39 cm between the two sticks is stretched flat and then sewn.

In this way, after the two sticks are sewn together, the original cylinder roughly becomes a half cylinder split in the middle.

Then sew the base that was cut out to the bottom of the semicircular cylinder, and the main body of the backpack is sewn.

One thing that needs to be explained is that what is combined with the bottom is the section where the edge of the stick is flush with the half cylinder.

At the end of the stick that was ten centimeters away, Han Cheng used an awl to pierce holes near the upper edge, and threaded a rope through these holes.

In this way, you only need to pull the two ends of the rope together, and the upper opening of the entire backpack will shrink together, and then tie the rope, so you don't have to worry about something falling out of it.

When sewing the entire backpack, according to Han Cheng's request, Bai Xuemei didn't use a needle, but pricked holes with an awl first, and then threaded it out with a small leather rope.

The backpacks sewn in this way are many times stronger than those sewn with needles and threads.

Whether it looks good or not is the second thing to do, as long as it is strong.

After all, this time it was used for a long-distance trip. If it is not strengthened, it will be embarrassing if the bottom of the backpack suddenly falls off halfway.

After the body of the backpack is sewn, start sewing the backpack straps.

Backpack bags are no longer sewn from a single layer of leather, but from two layers.

Because the weight of the entire backpack will be added to the two straps at that time, it is necessary to use double layers.

While sewing the backpack bag, Han Cheng found some soft grass and asked Bai Xuemei to sew the inside of the backpack strap.

And the backpack is very wide.

The purpose of doing this is to reduce the pressure on the shoulders, so that people's shoulders will not be too painful from being strangled.

After Bai Xuemei sewed the two bags on, Han Cheng put them on his back for a try, and found it to be okay and comfortable.
