1. Start with a small slipknot on the needle, weave the black thread three times and the blue thread the next time and then the next time. Remember to add needles every time you change the thread, as shown in the figure, the double-color thread will weave 27 times.
2. Add one stitch to the blue thread, drop five stitches to the left, and then turn back to knitting.
3. Drop 3 stitches in the remaining rows, and then turn it upside down until there are 5 stitches left. Then change the black thread and weave back and forth.
4. Next, start to weave the pattern of the upper, and don't add needles at this time. After the pattern is completed, the black thread weaves back and forth, and the blue thread weaves 5 stitches and returns, and one stitch is received for each stitch change. On the basis of the previous row, other rows knit 3 more stitches to the left, and the last row knits 5 more stitches. After picking all the stitches on the left side, the right side will continue to walk 1 stitch at a time, and the upper will be completed by the remaining three stitches.
5. Finally, sew the sponge directly on the sole and sew the shoe mouth, and a pair of rabbit wool slippers will be finished.
