Someone was attempting to personalize a t-shirt with the name יהודה and unfortunately erred and put the ד at the end after the ה, thus unwittingly causing the name of Hashem to be written on the back of the t-shirt.
Being that it was done unintentionally, can:
1. The t-shirt be discarded.
2. Edit/revise the lettering to either separate the letters or change the lettering so that the letters of Hashem’s name no longer appear.
Thank you very much
In the future he should be careful whenever writing the name Yehuda, that his can happen. However in retrospect, now that it was done, since he never meant to write H-shem’s name, it does not have kedusha and it can be edited or revised.
