Chitting charlottes

Hi
I eagerly started Chitting some Charlotte potatoes a few weeks ago and they are sprouting nicely. What is a good size of 'chit' before planting? And do I plant chit down or up?
Obvious newbie!

Given that most seed spuds are somewhat egg-shaped and have chits all over the "rose" end (and sometimes over all the potato) I just lie them down when planting - some chits are bound to be up, some down, and some sideways! 

Looking at the three types of spud we are chitting, the Charlotte have the smallest chits, the Annabelle are a bit bigger, and the Lady Christl are even bigger, although we got them a couple of weeks later.

I suppose this is signal of the titles 'First Earlies' and 'Second Earlies', as Charlotte are the latter type. Presumably 'Main Crop' wouldn't be showing much at all at the moment?

My main crop have the biggest chits - about 2 inches and are looking like leaves they are purple as well so look amazing

 

I read that as Chatting Charlottes  ::)and thought "I dont know a Charlotte on the boards  Best check it out ...."  and find she has a good line in musicals!    Doh.
