Hello everyone, are you having a great day today?
Today, I’m excited to share with you an incredibly cool technique involving sketching and inpaint sketching.
Sketch and Inpaint Sketch
In this session, we’ll explore one of the unique features of WebUI Stable Diffusion – sketching and inpaint sketching.
While my previous post briefly covered inpainting, today’s focus is on functionalities that allow for sketching and incorporating color into your creations.
–> Go to Post (What is Inpainting)

The Sketch feature is ideally optimized for those who are not adept at drawing. You can simply create a rough sketch of what you imagine in your head, and then use this sketch to generate an image or modify an existing one. The Inpaint Sketch function is used to reprocess images by reflecting specific colors.
1. Image Generate
Let’s dive right in! For a smooth process, you first need to generate an image in Txt2Img. Combine your desired base model and LoRA data with a fantastic prompt to create a result. If you’re still finding it challenging to come up with prompts and settings, you can follow my settings shown below.
Settings
- Base Model: dreamshaper_8.safetensors
- VAE: Automatic
- Positive Prompt: 1girl, blond short hair, makeup, black eyelash, white sports bra under pink jacket, looking at viewer, black background
- Negative Prompt: letterbox, watermark, logo, worst quality, bad quality, badhandv4, ng_deepnegative_v1_75t
- Sampling Method: DPM+ SDE Karras
- Sampling Steps: 30
- Size: 512×512
- Upscaler :4x-UltraSharp
- CFG: 7
- Seed: -1

Once everything is set up, click on “Send image to Img2Img” located right below the processed image!
2. Img2Img Sketch
Now, your task is to sketch something new onto a specific section of the image you’ve brought in. To put it simply, this feature is particularly useful when you’re overall happy with the image generated by Txt2Img, but find a particular part lacking or unsatisfactory.
In my case, to depict accessories on the generated image, I’ll attempt to sketch with my admittedly not-so-great drawing skills… don’t be too shocked, haha.

As shown above, with the Sketch tab activated, moving the mouse while holding the left button down paints with a white ‘brush’ on the image.
You can adjust the brush size on the top right of the image, so feel free to sketch whatever additional elements you’d like to add. The important thing to remember is that you don’t need to be a great artist! Of course, once you’ve sketched, you should specify in the Positive Prompt what you want to be reflected in that sketch area. Shall I try generating the image now?
I added additional Prompts : ((golden sunglasses)), ((diamond cubic earring)), ((thick golden chain necklace)), ((golden rings))

Wow… I’m just amazed. Can you see how it has automatically processed the image in a way very similar to what I imagined?
I think those with better sketching skills or those who can draw using a tablet might be able to create even more precise elements.
Since I did this using a computer mouse… well, let’s just say it’s a bit rough.
This time, I’m thinking of adding some new elements to the background.
A plain black background feels a bit lacking, so how about I sketch a pattern of leaves? I’m already curious to see how accurately it will recreate the sketch I draw. Here’s a tip: you can change the color of the sketch you want to draw. If you look at the top right corner of the image, there’s an icon resembling a palette. By clicking on this button and specifying the color for your sketch, the image will be generated reflecting that chosen color. Keep this in mind as you experiment!

Can you see it..! The fact that anyone can create their own beautiful artwork, even if they are not good at drawing, truly brings me joy.
Now, moving away from sketching, let me introduce you to the second feature for today – Inpaint Sketch
3. Img2Img Inpaint Sketch
Inpaint Sketch prioritizes color over the form of a sketch. While color can be incorporated in the Sketch feature we just discussed, Inpaint Sketch primarily recognizes color and roughly follows the sketch accordingly. To provide a simple example, I drew a pink curved line on the same image and added the word “Water” to the prompt.
I added additional Prompts : water

Isn’t it fascinating? Unlike the Sketch feature, Inpaint Sketch heavily emphasizes the color I selected and shows the water effect. However, it’s slightly disappointing that not all the lines drawn over the figure are fully represented.
In reality, there may not seem to be a big difference between the two features, but depending on the situation and your customization needs, I recommend choosing either Sketch, Inpaint Sketch, or Inpainting (as briefly explained in a previous post) to suit your requirements. Even if you’re not familiar with drawing or aren’t skilled at it, these features can help anyone create stunning results.
