These bookmarks are an especially helpful resource to keep track of the changes in shemoneh esrei. They are meant to be inserted in the proper place in the siddur as a reminder of when to say mashiv haruach, morid hatal and tal u’matar. The bookmarks have the type of change on one side and the relevant halachos listed in point form in English on the other side. Available in Yiddish as well. These cards are l’ilui nishmas Binyamin Yosef ben Harav Yehudah (shlita).
