You can easily find the commands to use to create rectangles and circles. The location of the seams can be adjusted using CrvSeam. The other commands I used are included in Rajaa’s instructions.

Most participants in this forum are willing to help others learn as long as it appears those asking questions are also trying to help themselves. Learning requires work, not just copying what others have done.

If you use Rajaa’s method on a rectangle you will find where it does not work as you would wish. Then think about what would be needed to achieve what you want. After you have done that you will be able to better ask for assistance.

@davidcockey thanks a lot. I am working on it brother…after failing many times I asked here. I am also keen to learn. Thanks for ur suggestions. I appreciate it.
