First-and second-grade students' manual production refers to the following practices:

Preparation materials: used paper tubes, glue and colored paper.

Step 1: First, we find several paper tubes, which can be different in height and size.

Step 2: Then find some colored papers and choose and match them according to your favorite colors.

Step 3: Then stick the colored paper along one side, not too sticky.

Step 4: Then put the paper tube on the colored paper and roll it up from the beginning.

Step 5: After rolling up, fix the joint of colored paper with glue again, as shown below.

Step 6: Finally, decorate the favorite group on the paper tube. If you want to make a combined pen tube first, you can fix three paper tubes together, as shown in the figure.
