I wanted to make the handles with a bit of a curve to make the sewing easier. A roll of masking tape was handy so that’s what I used to draw the curve. Worked perfect.
Box the corners by taking the bottom corners and squeeze them so the seams meet. Stick a pin through all thicknesses at the seam line so that you know you are matched up. Once you have the seams lined up perfectly, pin in place. Mark a line at 1.5” from the point. Sew a couple times down that line to make sure you have strong seam.
However, it wasn’t the best bag for the 2 year old as she didn’t realize she had to open the bag in order to have the treats dropped into it. I thought the one handle idea would be a lot easier for her. It worked great for the 4 year old so do keep that in mind.
