Make a Collage

If you can’t decide on which photo to use, you can upload multiple images and create a photo collage. This can be done using one of our pre-set montage templates, or you can create your own entirely from scratch. It’s super easy to do and the possibilities are endless.

How to add your collage to your product

Step 1 – Click the start design button & select your product options.

Step 2 – Go to the ‘Images & Text Tools’ tab, click the ‘add images/Text’ button on your product & ‘Select Images to Upload’ or use the Facebook/Instagram tabs.

Step 3 – Choose the images you want to use for your collage, upload & select them from the uploaded photos list.

Step 4 – Click ‘Create montage’ & select your collage style.

Step 5 – Add the collage to your design.

Hints and Tips

  • The more images you add to your collage the smaller each image will be. Fewer images will be larger and give you more clarity and detail.
  • The more people in an image, the less detail there will be. If you have 10 images of a group of five friends, each person will be smaller than if you have 10 images of just one person.
  • Try to make sure that the longest side of each image is around 10 centimetres. There is a handy ruler built into the design tool to help you with this.
  • Smaller products will not be able to fit as many images as larger ones will.

No surface texture

Our expert printing technicians use a top-of-the-range digital printing technique to penetrate the eco-friendly inks deep into the fibres of your birthday t-shirts. This produces a full-colour print that will last for years to come, without that surface texture that you get with t-shirt transfers. The t-shirt keeps its original handle and displays your glorious photos in stunning high-definition.

Tips and tricks

We advise against trying to register design elements from the front to the back, such as horizontal stripes. We will try to align any obviously continuing parts of your design, but cannot guarantee 100% registration.


The colour and finish of our all over t-shirts are exceptional, we are sure you will be delighted with your order.

There are some limitations to our production method which are particularly apparent with designs containing solid colour. Some small white wrinkles can appear in the underarm area between the sleeve and the body of the t-shirt. This is to be expected to a small degree and whilst we will always try to produce your t-shirt without this unprinted wrinkle, it will sometimes be unavoidable.

With all over printing, there can be some fading where the collar meets the body of the t-shirt. This is only really apparent on dark/solid coloured designs. We will always try to reduce this but sometimes it is unavoidable. Some areas of the t-shirt may have small folded sections (typically 5mm-10mm in size) where the ink has not penetrated the fabric. We try to avoid this but depending on your design it is sometimes impossible for them not to feature on the t-shirt. Most of the expected flaws mentioned above appear in unnoticeable positions once the t-shirt is actually worn, under the arm for example. Only when performing spirited hi-5’s will they become visible.

We guarantee you will be so satisfied by the colour, saturation and detail that of your t-shirt, that any aforementioned flaws will hardly even notice. Three-year guarantee on print, material and stitching finish.
