I often hear my old calligraphy teacher (and so far only her) use something
like the following:

> 何々。。。書いてもらいなさい（？）
>
> 何々。。。やってもらいなさい（？）

and so on. The question mark in parenthesis indicates that, if I hear the
intonation correctly, it seems more like a kind request rather than an
imperative. Or at least, kind of in between a request and an order, exactly as
the the two forms suggest.

The meaning is quite obvious, I am mostly interested in the following.

**Nuances.**

How does this differ from simply using ーてもらえる？ ーてくれる？ or the ーなさい forms alone?

**Speech style.**

Is it something somewhat old fashioned? I'm asking just because as I mentioned
above so far I have only ever heard this from an old lady.

**Actual meaning**

I find it quite difficult to give a literal translation. Somehow, ーてもらえる? and
ーなさい seem almost opposites to me (one a request, one an order). Am I correct
in interpreting this as "please do this?", or is there a better way of putting
this?

If possible, I would also appreciate a few extra examples of usage.

**EDIT:**

Reading and thinking on a comment by @By137 I wonder if I misheard all this
time and wasn't actually 。。。て御覧{ごらん}なさい. Obviously rather than my poor
listening skills I'll say that this is due to my old teacher being very old
and speaking in very incomprehensible way... which is false. I'll ask myself
next time and eventually edit or close the question, although it could still
be a good question for the てもらいなさい form.

question

About the coupling of ーてもらう and ーなさい
~てくれる? Is a (casual) request, but it lacks demand. Which is why it's in a
question format. ~てもらいなさい is a demand used when talking to someone of lower
status then you. You can hear なさい when parents order their kids to do
something. She adds the questioning tone to not have a sense of reprimanding.
