Strip Grafting on a Gryphon

Post by Flame_Kurosei »

I couldn't find another topic on strip grafting specifically (though there's probably one out there) so I'm posting here....yeah..

I need help making a strip graft for this origami gryphon I found on the internet (link below)
http://www.instructables.com/id/How-to- ... n-origami/

I made the diagram quite a few times, and overall it looks great, but I wanted to make better toes for it instead of just flaps..you can clearly see them in the one I posted on Deviant art (link below)

This is when I found fishgoth's essay about adding toes. Link below
http://www.fishgoth.com/origami/essay_designing2.html

I've tried the point splitting method, and it doesn't work very well (the legs get either too short or the toes get too small), so I wanted to try strip grafting...problem is..I'm not sure where to begin..could someone please help me?

Step 1: Draw a crease pattern.

What matters is that you have the general polygons in the right places. You need to be able to tell what parts of the square will make what parts of the griffin. Only then will you know what parts need toes. You wouldn't want to add toes to the wing would you?

Alright....I made the CP but I didn't read what you typed until after I made it...so here it is anyway.

I must admit, the toes on wings idea does sound interesting...it might turn into a bat-gryphon then!

So sorry about the bad quality...I kind of just did it on some paper I had around...the head is on the top (north) part and the tail's on the bottom (south) for reference...

So the corners are the legs? If so you would use an X graft.

Edit: Actually there are a few ways to go about it. I'll draw up some pictures later…

I'm not sure if they are the legs...hang on, let me check.

Edit: Yes, the corners are the legs...what's an x graft?

These are the three types of grafts I would recommend. There are advantages and disadvantages to all, but these are the easiest ways to add toes without doing any actual design work.

For all, the toes go at the ends of the pleated areas. (should be 4 sets of toes in each)

The X-graft causes a lot of extra layer pileup in the middle of the paper. There are ways to collapse it nicer than simply cross-pleating, but there wiill still be extra layers there. An advantage is that the rest of the design really remains the same.

The U-graft allocates extra paper to the top or bottom of the square, in this case the top, twice the amount from each of strips on the right and left edges. You can use this extra paper to form a more detailed head, including color changes if you desire. Or you can just fold the entire top section in and out of view, then pleat the sides of the rectangle (the grafts on the sides) until it's a square, form the toes, and then fold the griffin as usual. The wings will have extra pleats.

The I graft has grafts at the top and bottom of the square, and a double-wide graft running vertically down the middle. It will cause extra paper to appear at the top and bottom of the square, so the head and tail will gain a little extra paper that can be used for detailing like in the U-graft.

You're on your own from here. I did not give you complete grafts on purpose. I just wanted to give you an idea of where they were.

Good luck!

I personally feel that the addition of toes seems rather unnecessary :/ the model is rather simple and adding toes would only add thickness to certain areas without actually adding too much to the actual model. Perhaps were the model more intricate or detailed, having toes would be a benefit, but in this case I feel like toes would just contrast the simplicity of the rest of the model.

but if its something you really want to do, I won't try and stop you. I just wanted to put in my two cents



and looking at your picture on DA, you said you used watercolor paper?? thats not usually a very good paper choice for origami ( it has its uses, but it probably shouldn't be your first choice :B)

Whoops...well, I don't really have any good paper at my house besides printer paper and notebook paper so thought it would be a good idea (it was kind of the only thing I had on hand -sweatdrop-)...Also because I wanted the paper to absorb the oil more. Besides, it wasn't actual authentic watercolor paper anyway, it was more like a hybrid between watercolor and sketch paper....do you think printer paper would have worked better?

About the toes..I just wanted to see if it would make the diagram a bit more interesting to look at, since everyone who sees it at my house always asks about why the feet are just flaps...if it doesn't look any better that's fine with me (it just gives me something to do in my spare time). Thank you origamimasterjared, by the way, for helping me out. If it turns out well (and if I remember) I'll post a picture.

It is a very simple diagram and I´m sure the grafts will make the layers still more apparent, depending on the actual type of graft the effect they will have.

Another thing you could try is to modify the model and strech the leg points more, what I mean by this is to deform the base to extend the leg points without altering anything else, getting that way a very similar pattern except you will lose the 22.5 degree quantization in your angles.I don´t know if this will be a little too difficult for you?

To add my two cents: the X type graft will be the one I would choose if I was to graft it because it will leave more room to work on the top of the head where you actually might want to add more detail, maybe enough to free the topmost point to use for other purposes maybe reproductive organs or teats.
The most important thing is tho have fun, try them all and post pictures, remember eaven if all of them look awful you will learn new things and techniques which will advance you more to better origami.

Have fun and post pictures
