Steps to make the Kaffe Hat Box Quilt

1. Quilt Block Background – Y Seams

Place the side wall and floor pieces right sides together so you have 4 sets. The floor pieces should be on top. Mark a dot 1/4” inside each corner.

Attach BERNINA Patchwork Foot #97D. Do you use the attachable seam guide? It’s a great option! Thread machine with Mettler Silk Finish Cotton thread. Align the fabric edge with the right edge of the foot. Use your Freehand System to help with exact placement.

2. Sewing along the raw edge

First, secure the start of your seam with a backstitch, then sew a 1/4” seam allowance along the raw edge slowing down as you near the marked dot. Your goal is to finish the last stitch on that dot. When the needle is in the dot, do a backstitch. Cut threads. Do same for other 3 sets.

Carefully press seams open. These are bias edges that stretch so do not move iron over fabric. Gently press.

3. BERNINA Patchwork Foot #97D

The BERNINA Patchwork Feet have notches saving you the time of marking fabric. Pictured below is Patchwork Foot #97. There are 3 notches on the left toe. The first one (see arrow below) is 1/4” in front of the needle; the middle one is aligned with the needle; the last one is 1/4” behind the needle. You will use the first notch to find your stopping point.

4. Engage Needle Stop Up/Down

Engage Needle Stop Up/Down so the needle stops in the down position. Find your back wall fabric square. Place the back wall fabric on top of side wall fabric right sides together. Align raw edges and sew 1/4” seam allowance. Stop 1/4” from the end which is when you get to the first notch on the left toe.

With the needle down, raise the foot and check placement. Ideally, the needle should be in the seam line of the mitered corner.

This is the tricky part. With the needle down and the foot still raised, move the fabric clockwise so the floor fabric (triangle print) is aligned with the 1/4” mark on the stitch plate.

5. Carefully place back wall fabric

Then, carefully place back wall fabric (green dots) over floor fabric so raw edges are even. Sew your 1/4” seam allowance to bottom.

Carefully press seams to one side as pictured below. What a beautiful Y seam! Now finish the other background blocks.

Finished block size is 12 1/2” x 12 1/2”.
