I'm just learning to read Hebrew, and I discovered that the text I use for Kriat Sh'ma al Hamitah contains G-d's tetragrammaton, yud kei vav kei. I'm afraid of accidentally using the Ineffable Name. Any ideas? I was wondering if covering it with a sticker is permissible?(in a manner which the sticker can be removed without damage to the original text i.e. on a laminated card)
Thank you very much.
