1.15 Full & Flat Bottom Adjustments (Trousers)

Tuesday Techniques!

This video covers one of the areas that I find most challenging when fitting trouser patterns - the bottom. The problem with this area is that we are trying to fit in 2 or 3 different planes so it is no surprise that this can often take a few gos to get right.

If you carry more weight around your bottom then you may find that your trouser toile is too tight in the back crotch aka "hungry bum" and so it can help to increase the length of the back crotch as well as the width across the back hip.

If you have a smaller, flatter bottom you may find that you end up with excess fabric at the top of the back thigh area and some looseness in the side and back hip.

If you have struggled with either of these issues then a full or flat bottom adjustment may be just what you need to tweak your pattern for your particular body shape.

In this Tuesday Techniques session I explain

  • how to assess your body to see if this is an adjustment you might need

  • how my own toile shows that this adjustment is necessary

  • how to make the pattern adjustments on your pattern piece

If you have a pattern that you want to work on then why not give these modifications a try as you watch the video.

If you want to find out more about how to make a toile then check out this post: What is a toile and why do I need one?

If you have a pattern that is not a simple pair of trousers like the ones in these examples and would like pointers on how to apply this change to that specific pattern please let me know either in the Facebook Group or by email and I can share some tips and techniques to help you tweak this process for your garment.

If you have any questions then I love to help so email me at and if you have any a-has or inspiration from this session let me know in the comments below.
