A. Bottom Triangular Panel (Main Body Start)

Magic Ring and First Row

Every row will be worked in BLO.
Row 2 - Begin Shaping Triangle

- Second stitch: 3 sc in BLO of the second stitch (this becomes the tip of the triangle).
- Third stitch: 2 sc in BLO of the third stitch (inc).
- You now have more stitches, forming a small triangle point with a central "tip" of 3 sc.
Row 3 - Establish Repeated Pattern
The designer explains the consistent pattern: increase at first stitch, 3 sc at the middle "tip," increase at last stitch. The number of single crochets on each side (between edge and tip) grows gradually.

B. Begin Decreases for the Front Flap Shape (Row 7 onward)

From Row 7, the narrator starts decreasing at the first and last stitches instead of increasing, while maintaining 3 sc at the center tip. The pattern:

First and last two stitches: sc dec in BLO.
Middle tip: always 3 sc in the tip stitch.
The number of side stitches between decreases and tip remains steady once established.

Row 7
- Ch 1, turn.
- Dec over first 2 stitches in BLO.
- 1 sc BLO in next 9 stitches.
- 3 sc BLO in tip stitch.
- 1 sc BLO in next 9 stitches.
- Dec over last 2 stitches in BLO.

- 1 sc BLO in next 9 stitches.
- 3 sc BLO in tip stitch.
- 1 sc BLO in next 9 stitches.
- Dec in last 2 stitches.
Continue in Pattern
- Ch 1, turn.
- Dec at beginning (2 stitches).
- 1 sc in each side stitch.
- 3 sc in tip stitch (center).
- 1 sc in each side stitch.
- Dec at end.

C. Single Crochet Border Around the Edges

Once the main triangle piece is complete:

Weave in Starting Tail
- Weave in the initial magic ring tail securely.
Work Border Along Edges
- Attach yarn at one side edge near the bottom.
- Ch 1.
- Work 1 sc in the end of each row along the side, in a consistent manner:
  - Use a stitch marker to mark the first sc.
  - Identify each "row end" and insert hook to create an evenly spaced edge.
- The narrator has 54 sc from start to last row on one side; your count may differ depending on row count.
Corner Treatment
- At each bottom corner: work 3 sc into the same point to round the corner.
- Continue sc along the bottom edge.
- At the opposite bottom corner: again work 3 sc into the corner.
- Continue up the other side edge with 1 sc per row end.
Slip Stitch Round and Button Loop
- After reaching the top edge, begin working slip stitches along the top for a neat finish.
- Before reaching the very tip of the flap:
  - Ch 10 to form the button loop.
  - Skip the tip stitch.
  - Sl st into the next stitch to anchor the loop.
  - Adjust chain length if your button is larger or smaller.
- Continue slip stitches across the remaining top edge.

D. Fold the Bag and Join Sides (Reverse Single Crochet / Crab Stitch)

Determine Fold Line
- Measure your phone and fold the piece so that:
  - The bottom edge aligns to form a pocket.
  - The top triangle covers the phone when folded down.
- Use stitch markers to align side edges.
- Save
Join One Side
- Position the bag so you can work from bottom to top on the side.
- Attach yarn at the bottom side.
- Work reverse single crochet (crab stitch) through both layers (both loops of both side edges) to join the sides:
  - Insert hook through both loops of both pieces.
  - Pull up a loop.
  - Yarn over and pull through both loops on hook.
  - Move one stitch "backwards" and repeat.
- Continue up the side to the top edge.
- Cut yarn, weave in end.
Join Other Side
- Repeat the same crab stitch method on the other side, working from bottom to top.
- Cut yarn, weave in end.
  Save

E. Attach the Button

Locate Button Position
- Place your phone inside the bag.
- Fold the flap down and align the chain loop.
- Mark the point on the front body where the button should sit so the loop fits snugly.
Sew Button
- Thread a strand of yarn or matching sewing thread.
- Sew button securely at the marked spot.
- Test closure by looping the chain over the button; adjust if needed.
  Save

F. Make and Attach the Strap

The strap is a slim, reinforced single crochet strip.

Begin the Strap
- Leave a long tail at the start for sewing to the bag.
- Make a slip knot.
- Ch 3.
Row 1
- Work 1 sc in each of the next 2 ch (total 2 sc).
- Turn.
Row 2 and Onwards
The narrator describes a method that alternates between working into a single stitch and then into a pair of loops to keep the strap neat and strong. A simple way to express it:
- Each row:
  - Skip the first stitch.
  - Work 1 sc in the second stitch.
  - Insert hook into the loop(s) at the side edge of the strap (the two loops she points out).
  - Yarn over, pull through those loops, then yarn over and pull through 2 loops on hook.
  - Turn.
Finish Strap
- At the end, leave another long tail for sewing.
- Cut yarn.
Attach Strap to Bag
- Use a darning needle.
- Sew one strap end securely to one side of the bag near the top.
- Sew the other end to the opposite side at the same height.
- Weave in tails thoroughly.
  Save

Tips and Customization Ideas

Size Adjustments
- If your phone is smaller: work fewer rows in the main triangle, and place the button lower.
- If your phone is larger: add more rows before you begin decreasing, or continue the pattern longer, and extend the strap or adjust button placement accordingly.
  Save
Button Loop
- Alter the chain length of the loop to match different button sizes or to allow for fingers to slip through as a small wrist loop.
Texture
- Back-loop-only stitches create raised lines that make counting easier and give a structured look. Keep your tension even for a clean, crisp triangle.
  Save
