minhag - Rav Scheinberg and Tzitzis (series of questions)

I have heard that Rav Scheinberg wore many garments with ציציות on them at a time. . .

• Is this true?


• If so, why did he do it?


• If not, why do other people do it?


• How many ברכות do they make when putting them on?


• If the answer is >1, at what point in the putting on process is the 2nd ברכה made?
