If you have a Brother embroidery machine that has the Snowman feature, PLEASE start using it! It will change your life!
I did a quick video a couple of years ago (while working on hankies for the lovely Amanda Cookson at Southern Bride) on how I use it to save me a mountain of time with lining up my designs.
I used embroidery software to print out the template of my design with the snowman marker already on the design. You can also use your normal method to find where you want to place your design on your item, and use one of the stickers and stick it so the cross hairs line up with the vertical and horizontal centres of your design.
If you have any questions about using the Snowman feature, ask in the comments below and I’ll help you out.
