I made this bag with Moda Dea Beadnik yarn in chocodelic color. Because of the little beads in this yarn, I wouldn't recommend using this yarn unless you were going to line the bag. The beads will scratch the cell phone.
Other materials needed:
*Make sure to measure the bag against your cell phone or other items you want the bag for. I made this to fit my cell phone and still have some space, but cell phone sizes vary.
Row 1: Sc in second chain from hook and in each chain across (14 sc) Chain 1, turn.
Row 2: Sc in each sc across, chain 1, turn.
Repeat row 2 for desired length, minus two rows. Do not finish off! I made mine long enough to go around my cell phone and still have a flap.
Second to last row: Sc in first 3 sc, chain 2, skip 2 sc (button hole made), sc in next 4 sc, chain 2, skip 2 sc (next button hole made), sc in next 3 sc, chain 1, turn. The rule for this row is this: Determine how many button holes you need. I did two because I wanted to use two buttons. I had to decide how far apart the buttons had to be. If you are just using one, make the button hole in the center, if you are using two, it's a little tougher. Whip out those math skills and put them about a third from the side.
Last row: Sc in first sc and in next 2 sc, 2 sc in chain space, sc in next 4 sc, 2 sc in chain space, sc in next 3 sc. Do not finish off. The rule for this row is this: Work sc in each sc to chain space. Work the same amount of sc as their are chains that make up that space (I did 2 sc because I had 2 chains). Sc in each sc to the end. (If you have two button holes, just repeat the entire row to the end.)
In same space as last sc, work two more sc (corner made). Sc in each row down the side, 3 sc in corner, work 1 sc in each of the free loops across the bottom, 3 sc in the corner, and work sc in each row up the other side, 3 sc in last corner, join with sl st to first sc in that row. Finish off. (You do not need to work across the top of the project to the other corner because that is already a row of sc. You can do it if you want.)
Strap and side seams:
Fold as desired, making sure to place the phone (or other objects) inside to make sure you get the right height for the phone. Starting at bottom of right side, join with sc to first 2 sc (that are now across from each other). Sc up the side, making sure to work through both sc of edging as you go.
When you reach the top, start a chain. Make it as long as you want your strap (or twice as long as it will be folded to attach to the other side of the bag). When you reach that length with your chain, sc in second chain from hook and in each chain back, then turn and work a sc back up the strap in the free loops on the other side of the chain (it's like crocheting a border in the free loops). Your other option would be to just sl st back in each single crochet. The point of this is to make the strap sturdy and get you back to the other side so you don't have as many ends to weave in.
Do not twist the strap and make sure the "pocket" of your purse is straight. If it is, join the strap with a sc at the beginning of the seam on the left side. Work sc down the side (working through both sc) to the bottom. Finish off.
To add buttons, cut a length of yarn about 8 or 10 inches long. Begin to weave it in a few rows above where the buttons will go. Weave in a few inches. When you get to where the button should go, put the needle through the button hole and pull the button down to the work. Make sure the button is lined up with the button hole before continuing. Continue weaving until the yarn is gone. This should secure the button well. (If you use two buttons like I did, do the same with the other button, but be sure to weave the yarn through the work to the next button space before putting the button onto the yarn.)
Weave in ends.
Sorry it's hard to understand. It was easy to make and it sounds more complex than it really is.
