Time: It varied. I had to get used to working with FOE. The covers with gussets are more time consuming.
I also made my favorite cover for Elijah. I made a new pattern using gussets, and a different snapping layout better suited for a cover and sized it to be medium. I was really afraid I wouldn't like it, but it turned out great! Yay, I ended up with something that fit Elijah right!
So my last project in my FOE adventures were two side-snapping covers. For the first one I drafted my own pattern from Eli's measurements and my trainer pattern. The the second one I used the free Chloe Toe's pattern. My pattern was tiny compared to her's (but I didn't find the notice to take and inch off the width until after I had cut the PUL). In the end, both patterns turned out a diaper about the same size. I should have tightened the front waist of the CT pattern more, but that was my fault. The CT diaper has a lot more room for "fluff" than mine, which I don't like, but I do like the stretch on the legs of hers much more. I still have some work on my pattern, but that will go on the back burner since I don't like side-snapping covers much anyway :-/
One thing I am bummed about is the FOE has been getting really pilly when it comes out of the dryer. Many times I find an aplix tab of another diaper stuck to the FOE, even though I folded them in. I so don't like velcro!
