Help needed--trying to make digital paper w/chevron and dots

Help needed--trying to make digital paper w/chevron and dots
Hello!

Let me start by saying I am very much a beginner to Gimp and as such I don’t know much about the program at all. I apologize in advance if my questions in this post seem incredibly dumb. I’ve tried to research the issue on my own but I’m just becoming more confused so I thought I’d post here.

I am attempting to make some digital paper in 8.5x11 size for a project I am working on. Ideally, I would like to make some paper that has a polka dot pattern and a chevron pattern (separately.) I’ve figured out how to do the chevron pattern in 2 colors, however, I can’t figure out how to get more than 2 colors in my pattern. For example, if I wanted to do red/blue/yellow/green/white or another combination of colors, how would I do that? I’ve seen multi-colored chevron digital paper so I know it can be done but I’m just not sure how?

When it comes to the polka dot pattern, I’m still working on that. It is more confusing to me but I think I will eventually get it. My question is the same though—how would I get the polka dots themselves to be different colors with a white background? I think I can figure out how to get for example a red background with white polka dots but I can’t figure out how to do a white background with different color dots.

I would greatly appreciate any advice anyone would have on this topic. Right now I’m at a loss and getting frustrated. Thanks in advance!

RE: Help needed--trying to make digital paper w/chevron and dots
Thanks so much for responding. That is sort of what I mean by the dots not being all the same color but is there any way to specify what dots are what color? Can the size of the dots be changed? I'm not sure how to use this....

Also for the chevron is there anything similar?

RE: Help needed--trying to make digital paper w/chevron and dots
other ways

Gmic plugin has quite a good 'polka dot' script., only one colour.

This one a 'generic' grid of dots.
make a grid, blur the grid
apply threshold
then whatever you want to do.

having a tidy up - everyone finished with this ...going..going..gone

RE: Help needed--trying to make digital paper w/chevron and dots
Thanks for the replies—I’m so new to this that it all sounds like a foreign language. I am really frustrated! I wanted to teach myself how to do this but now I’m thinking I might just buy some premade digital paper, though I don’t like that thought.

Like I mentioned before, my ultimate goal is to make a few different chevron and polka dot patterns. I would like to have a few different patterns—some where the chevrons are thicker, some where they are thinner. Same goes for polka dots.

To practice, I made a chevron pattern in red and white. This is probably a big newbie mistake, but I thought after I made the pattern, I would be able to click on the fill tool for either the background or foreground (depending on what chevron stripe color I wanted to change) and click on each individual stripe and modify the color stripe by stripe. It sounds tedious but I don't know any other way.

I thought this would work because I found a sample chevron pattern and played around with it and this worked, filling the stripes in piece by piece. Except when I made my own, it doesn't. Whatever color I am working on just bleeds into the next stripe and so on. I really wanted to be able to make a variety of different chevron patterns and dots eventually.
Also, a few questions:
How do I get rid of those lines at the top that look black?
Should I use pixels or inches for measurements or does it matter?
What resolution is best? I am going to be printing this and using it like a paper. 300 dpi x 300 dpi?

Thanks so much for reading!

Update: I think I figured it out. Well at least how to make each stripe a different color.

Though how do I make the individual stripes thinner and increase the space between them? I have tried playing around with the width, spacing and offset but when I change them, everything starts looking really odd.

Thanks!

Best not to get too confused, it all comes straight with time. If you keep on experimenting you will come up with something.
Just throwing a few thoughts around

This is probably the way you did your chevrons, but as an example more dots Wink

You can make a small image of anything, use a transparent layer and turn the background off.
Copy that and it becomes both a clipboard brush and a pattern

Now you can open a new canvas, the default stationary sizes are 300 ppi (that answers one of you worries, and Gimp does work in pixels) As before best to make a new layer.
Use the clipboard pattern to fill that layer. A quick way to fill is click on a pattern icon and drag into the canvas.

Colouring in, Well you could make a selection as in my video (link works now) or something like this A new layer on top, I used text but you could just draw.

Then set the layer mode to some thing other than normal. This is screen mode. Might not be the effect you want but wth, trying to keep it simple.

Yes, if you want to print, 300DPI is a good definiton. Once you have set the image print definition (preferably when you create it... because Gimp will compute the required size in pixels (see advance options in the File>New dialog)) pixels or inches are strictly equivalent (but keep in mind that your screen, which has a definition around 100DPI, will show things three times as big as in print at zoom factor 100%).

Attached is a copy of the rainbow chevron I just made. I'm not 100% happy with it---but at least I'm making progress? Confused

Ideally I would like the chevron stripes to be thinner and the points to have a little more definition to them. If more of the white between the stripes could show that would be great too. Right now it just seems really busy.

Something I have noticed when I'm playing around with the period, amplitude and phase shift is that if I go to make changes (after the first attempt) often it messes the stripes up. It is very weird. Not sure what is going on there.

Actually, I'm working on dots next, so this is great! Will go check out the video next. Those dots are exactly the size I was thinking for one of the patterns. I'm going to attempt to do this with that exact pattern, just multi-colored (hopefully).

If I wanted to attempt a slightly different dot pattern, such as changing the space between the dots or making them bigger or anything like that, would that be difficult?

I really appreciate the help from both of you---last night I was so frustrated and super close to just giving in and buying a pre-made paper pack. Now I think (fingers crossed) that there is light at the end of the tunnel.

No, you just make a bigger pattern image, with a smaller dot inside. The size of the pattern image it the "stepping" in the pattern-filled image.

Good to know--thanks.

I just made a polka dot pattern and I know I saved it as a .pat file. I saved it to my desktop and then moved it to the pattern folder in GIMP. I closed GIMP and restarted but the pattern is still not found. Am I missing something here?
