Before I actually read the lyrics to the song i thought the line "only love is all maroon", was really "only love is on the loom". Although this isn't correct (at least not that I know of), it makes it interesting. The meaning of loom is to seem imminent (likely to happen soon), or impend (threaten to occur). Another definition is "to come into view as a massive, distorted, or indistinct image". Kind of cool. Think about it.

A loom is also on object used to weave yarn into cloth.

i thought it was:

i am my mothers only one,
"that's" enough

and i thought it was:
only love is "on the rue"

This song i feel is about his relationship with his mother,

I believe that I wear my Garment so it shows is not a refrence to his heart on his sleve, i believe it is his pride in his orgins (mother)

Only love is all maroon i believe that he believes that the only real love which exists is that between family, those with which he shares blood which could be depicted as being maroon

I believe that gluey feathers on a flume refurs to animals being born, as gluey would indicate how they are born, and the flume being the vagina (assuming they do not hatch).

I believe i am my mother on the wall is him being in the uterus and moving `wall to wall` while being inside.

Finally Sky is womb and she`s the moon to em atleast displays his affection for his mom and i think he is stating that she is untouchable and superior.

Dam i wish he toured in Toronto.

Great Song. Shiver down my spine every time. If Bon Iver lyrics is an art movement, it will be most similar to cubism. He takes simple and arguably ordinary lyrics, chop them up, stitch them loosely together with his amazing vocals. So instead of one meaning, listeners can interpret the song their own way. They hear what they feel. For example, "i am my mother's only one, and its enough. i wear my garment so it shows". I have many siblings, so my mother never knit us clothing. I wished my mother could spend more time with me. Justin wore the garment his mother made.

In my head this song is about a mans relationship with his mother - the first line, for some reason allways have me think that he believes, or excuse himself for believing, that no other woman (girlfriend) will ever be really necessary in his life: "I am my mother's only one. It's enough". He is the only child, or at least the only son. I picture the character to have lost his mother at an early age, but he imagines her still being with him in some way ("I am my mother on the wall, with us all"). Her picture hangs in a frame on the wall, keeping the memory of her alive. Regardless the interpretation, this song is perfection.

Lots of good ideas here, here's a new take. First, remember where he comes from/where this was recorded - upper mid-west, land of 10,000 lakes, in a hunting lodge. I think this song is based on several observations of the landscape/nature around him, particularly based on watching loons on a lake. Some of his other songs include Wisconsin, wolves, and the woods as subject matter.

It seems clear to me that this song is about the nature he observed, in particular that surrounding or on a lake, with particular attention paid to the loon.

Let me explain:

I am my mother's only one
It's enough

(Here he sees a gosling with its mother, only one gosling, it's enough for the mother)

I wear my garment so it shows
Now you know

(Here he speaks of the gosling's feathers, or some other animals feathers/fur/skin, keeping with the observation theme, could be a reflection on how he or others often hide their true feelings/meanings)

Only love is all maroon
Gluey feathers on a flume

(Like everyone this is open to some many interpretation [maroon from a sunset maybe?], but I would point out that even the groove down the back of the loon could be the "flume", anything really that is "V" shaped, so gluey feathers on a flume could be the loon feathers.)

Sky is womb and she's the moon
(The sky, where the loon fly, is the womb, and the mother or water is the moon. Alternately, the moon reflects the light of the sun and orbits around the earth so he could be referring to the mother loon as the source of light to the gosling or referring to the gosling as orbiting around the mother loon)

I am my mother on the wall, with us all
(He's in a hunting lodge so I immediately assumed he referring to a stuffed duck/loon/bird on the wall)

I move in water, shore to shore;
Nothing's more
(Referencing the simple life of the loon)

Only love is all maroon
Lapping lakes like leary loons
(lapping here refers no doubt to the water lapping on the shore, but lapping has deeper meaning:
1 a : to fold over or around something : b : to envelop entirely : swathe
2 : to fold over especially into layers
3 : to hold protectively in or as if in the lap : cuddle
4 a : to place over and cover a part of

So he could be allegorizing the protective and leery mother loon)

Leaving rope burns --
Reddish ruse
(this could refer to actual rope burns from when he was on a lake using a rope, or it could refer to the ripple from the loons swimming or landing on the water in the sunset, the original definition of ruse is "a roundabout path taken by fleeing game".

Here's a theory:

When coupling the lines "sky is womb and she's the moon" and "I move in water shore to shore" I start to think of tides, which are determined by the moon. I think that it's a metaphor for how his emotions are tied to her movements. This also helps explain the line "lapping lakes like leary loons". And I agree with HopeSoForYou that "gluey feathers" refers to the loons' feathers' color on the water. Ultimately I agree with pretty much everyone else about the importance of "reddish ruse" and "maroon" in symbolizing the often harsh realities of love.
