  • ½ Yard 45” fabric for outer bag

  • ½ Yard 45” fabric for lining

  • 1 Yard 1” wide webbing for handles

  • 2 pieces of RNK Sew Fab Foam- 13”x15”

  • 2 pieces of RNK Hot n Cold Barrier Fleece- 13”x15”

  • 9” of 5/8” wide Velcro

  • Standard Sewing thread to coordinate with outer bag and lining- I used white for both

  • An embroidery design for front- about 4”x4”. I used a design found on Etsy from the “EmbroideryEasy” shop. Here is the link to the shop:

  • Floriani Embroidery thread for your design.

  • Fabric Marker

  • 2 pieces of Floriani Heat n Sta tearaway stabilizer 10”x13”

  • A piece of Floriani Water Soluble topper to cover your embroidery design.


  • From outer bag fabric cut 2 pieces 13”x15”

  • From lining fabric cut 2 pieces 12 ¾”x14 ¾”

  • From RNK Sew Fab Foam cut 2 pieces 13”x15”

  • From RNK Heat n Cold fleece cut 2 pieces 13”x15”

  • From 1” webbing cut 2 pieces 16” long


  • On one piece of the outer bag fabric, mark the vertical center. The 15” direction is the left and right side of the bag. The vertical center would be 7 ½” from each side. Mark down from one long side 5 ½”. The edge you measured from is the top. This is where the embroidery will be centered

  • Prepare your embroidery design. Add any lettering as desired.

  • Fold and crease on the vertical and horizontal lines you marked previously. From the backside, center one piece of the Heat n Sta over the creased lines and fuse to the back.

  • Hoop using the marks on your hoop to line up with the marks on your fabric. Remember that the 5 ½” marked space is the top of the bag.

  • Slide the other piece of Heat n Sta under the hoop before you begin embroidering and lay a piece of water soluble topper on top.

  • Embroider your design.

  • Remove water soluble topping and tearaway the Heat n Sta.

  • Press your embroidery design from the back side. When pressing from the front use a pressing cloth.

Bag Preparation:

  • From the fabric side, press the RNK Sew Fab Foam to the backside of both pieces of the outer bag fabric.

  • From each bottom corner mark a square 2 ¼”x2 ¼”. Cut out the square from each corner.

  • On each side and the bottom mark 2 ½” from the 3 edges of both pieces. Not the top.

  • Top stitch on the 2 ½” lines on both pieces.

  • Measure and make a small mark 2” from the stitched lines, into the center, on the top for placement of the handles. Mark from both sides and place each end of the handle inside the marks. Make sure to not twist the handles. Baste the handles to the bag with a ¼” seam.

  • Place both outer bag pieces right sides together matching sides and bottom. Using a ½” seam allowance, stitch both sides and the bottom of the bag together. Press side seams open.

  • In the bottom corners, where the square is cut out, fold the side seam to match the bottom seam. Pin together and stitch using a ½” seam allowance. Trim seam allowance to ¼”.

Bag Lining:

  • Repeat the following for both pieces. Place the lining fabric on top of the Heat n Cold Barrier Fleece. The Fabric will be slightly smaller as it was cut smaller. It was cut smaller to accommodate the thickness of the foam and fleece. Adjust the fabric to fit the fleece pin and baste ¼” around all edges.

  • Mark the following on both pieces:

  • Quilt the Hot n Cold barrier fleece to the lining on the marked lines.

  • 2 ½” from one long side, 3 ½” from previous mark and 3 ½” again from previous mark. Mark 5” from each side.

  • The 2 ½” marked edge is the bottom. Measure a 2 ¼” square in each bottom corner the same as the outer bag and cut out the square.

  • Place both lining pieces right sides together and using a 5/8” seam allowance stitch ONE SIDE and the bottom. On the other side, stitch leaving a 6” opening for turning the bag.

  • Press the side seams and bottom seam open. Press under the 5/8” seam allowances on both sides of the opening.

  • Fold the corners the same as the outer bag and stitch the corners using a 5/8” seam allowance. Trim the seam allowance to ¼”.

  • Turn the lining right sides out.

Bag Construction:

  • Place lining inside the outer bag. Right sides should be together. Keeping the handles down inside the bag, align the top edge and pin together. Using a ½” seam allowance, stitch around entire top edge. It would be handy to use your free arm on your machine for this.

  • Turn the bag right sides out through the hole in the lining. Poke out the corners on the lining and the bag.

  • Fold the opening in the lining, pressed edges together and using a very narrow seam, stitch the opening closed.

  • Push lining into bag and press the seam flat on the top edge. Top stitch ¼” around the top using the free arm on your machine again.

  • Place Velcro on top centered between the two stitched lines. Stitch the top edge of one piece of Velcro and down one short side. It will be easiest to stitch the second side by starting again at the same end you began so you won’t have to turn the bag around.
