Mini Briar Variation // Add a Lace Triangle Insert to the Back

Mini Briar pattern hack // Lace insert back

Hi! My name is Michelle and I blog over at Sewnhenge, but today I’m excited to be here with Megan Nielsen to show you how to make a fun lace triangle cutout to the back of the Mini Briar. You could also use a regular knit instead of lace to make a color block.

All you need is the Mini Briar pattern and all the usual sewing and cutting supplies. The only pattern piece you will be making changes to is the back piece.

First you will need to make a cut on the pattern where you want your triangle to be. I just took a straight edge ruler and make a line from the height of where I wanted it down to the width on the bottom. Then cut those pieces apart.

Don’t forget to add your seam allowances!! Instead of cutting that side piece on the fold, add 5/8″ seam allowance and cut 2.

Mini Briar Triangle Cutout step 3

For the triangle piece, you’ll want to cut the middle on the fold but add a 5/8″ seam allowance to the sides.


Take one side piece and line it up with the triangle, right sides together. Sew along where the dotted line is.

Then just take the remaining side piece and sew it to the new piece. You will have to pivot your sewing line at the top of the triangle.

Et Voila!! You have your new back piece with this pretty little lace triangle cutout!

Now just sew up the rest of the shirt as per Megan’s instructions :)
