Diamondize Some Text Given an input string of length 2 or longer consisting solely of alphabetical characters [A-Z] or [a-z] (your choice if they're all uppercase or all lowercase), output a continuous string of characters forming a double diamond pattern.

The input string starts on the center line and extends down-and-right at a diagonal until the end of the input string is reached. Then, the pattern continues up-and-right at a diagonal until you're as far above the center line as the length of the input string minus 1. Continue down-and-right back to the center line, then down-and-left, then up-and-left (going "behind" the center character), and finally down-and-left back to the starting character.

That's a little wordy, and it's better demonstrated by some examples:

"YOU"
  U   Y
 Y O U O
Y   O   U
 O Y U Y
  U   O

  ^   ^
 ↙ ↖ ↗ ↘
↘   ↗   &gt;
 ↘ ↗ ↖ ↙
  V   V


See how the YOU starts at the center line and follows down-and-right, then up-and-right, etc., until it loops back to the beginning. Note especially how the Y on the up-and-left portion is "behind" the O and therefore not shown.

Some further examples:

"HI"
 I I
H H H
 I I

"TEST"
   E     E
  S T   T S
 T   T T   T
T     S     T
 E   E E   E
  S T   T S
   T     T

"HELLO"
    L       L
   O L     E L
  H   E   H   O
 E     H O     H
H       L       E
 E     L L     L
  L   E   L   L
   L H     E O
    O       H





Input and output can be given by any convenient method.
The input is guaranteed to be at least two letters long (i.e., you'll never receive "" as input).
You can print it to STDOUT or return it as a function result.
Either a full program or a function are acceptable.
Any amount of extraneous whitespace is acceptable, so long as the characters line up appropriately (e.g., feel free to pad as a rectangle).
Standard loopholes are forbidden.
This is code-golf so all usual golfing rules apply, and the shortest code (in bytes) wins.

ＧＨ&lt;↗↘&gt;↖↙ＬθθＧＨ&lt;Ｌθθ


Try it online! Link is to verbose version of code. Explanation:

ＧＨ


Draw along a path.

&lt;↗↘&gt;↖↙


Draw in the directions ↘↗↗↘↙↖↖↙ (the &lt; and &gt; are shorthands for those two pairs, but the other pairs don't have shorthands.)

Ｌθ


Each path segment has the same length, including the ends, of the length of the input.

θ


Use the input as the text to be written along the path.

ＧＨ&lt;Ｌθθ


Print the first two parts of the path again so that the middle character is correct.
