Gimp is a free program which you can use to create your designs. To download your copy please visit
For this tutorial we are going to create a Polka Dot pattern with a green background and white dots.

Once you have installed GIMP on your computer you need to decide on the size of your design. For the purposes of this tutorial we'll assume you want it to cover 1 metre of our plain cotton. To do this you will need to create a new canvas by clicking on File > New. As the printable area of our plain cotton is 146cm x 100 cm you will need to click on the dropdown box and select cms, then enter the measurements (you will notice they will appear as 146.016 x 100.008 which is fine).

Then you need to click on Advanced Options and enter 150 pixels for both the X and Y resolution. It is important to keep it on the default setting of landscape and RGB colour space.

As you are creating a large file GIMP will ask you to confirm by clicking OK. First we need to add a green colour to our canvas. To do this use the Bucket Fill on the tools option and then click on the foreground colour. Change this to green and then click OK. You can then click on the canvas which will turn green.

Next we need to create a polka dot pattern. Make a new file by clicking on File> New. This time change the size to 3.5cm 3.5cm (again the measurements will be slightly out) but still keeping it at 150DPI and RGB colour space. Now we need to make a transparent layer. To do this go to Layer > New Layer > Transparency > OK

To make positioning the dots easier we'll create guides. Go to Image > Guides > New Guide (by precentage). Then make sure it states 50%, and Horizontal before clicking OK.

Repeat the process but this time select Vertical rather than Horizontal. To help position the dots you need to look at your settings. Make sure both Snap to Guide and Snap to Canvas Edge are active. To do this go to view and tick these if they are not already active. On the tools option select paint brush, and alter the brush to 100% Hardness with a size of 30 pixels.

Change the foreground colour to white, and make the background layer invisible by clicking on the eye icon next to it. You're now ready to place your dots on the canvas. Due to the settings you have chosen the brush will feel slightly drawn to the guides and edges, making positioning the dots easier.

With the polka dot pattern made, you need to save it. Go to File > Export and then change the extension to pat. Now locate the patterns folder in GIMP, then name your file before clicking export. If you are struggling to find the patterns folder you can go to Edit > Preferences. From here click on the + next to folders and then click patterns. You can now see where the directory is.

Close the window down, which should return you to your green canvas. From here click the refresh patterns button. You will now notice your polka dot pattern will appear as an option. Use the paint bucket and select your pattern and then change your fill type to 'pattern fill'. Then click on the canvas. Your polka dot pattern will now appear.
