Eight Shaft Twill Tea Towels

I put on this six tea towel warp to do some relaxing weaving and to have an easy project to work on while we were working on our house. House is complete and so are these tea towels, but I’ve got to say they were soooooooo boring to weave, it was a straight eight shaft twill and it got old pretty fast. I actually found it difficult to go to the loom, I just wasn’t into them at all! I've go to tell you that none of my photos came out with the right colour - they are much more yellow than they appear in my photos - mea culpa!I wove three of the towels with the same lemon yellow weft that was in the warp. I had alternated two yellows and this weft was one of them. These are really fresh looking and I like them well enough. I knew I had enough weft for these three towels and enough of the butter yellow for three more, but...As soon as I changed the weft to this butter yellow I knew this was destined to be the only one, it really looked peachy on the loom and I wasn’t sure I liked it. Turns out this colour became my favourite after washing! Go figure. I hunted through my stash and found this darker yellow and so this became weft number three. I liked it on the loom, but found that the stripes came out reading a different colour. I used the same green for my stripes as I used in the warp, but when it crossed this dark yellow it seems to read bluer somehow.
I didn’t love any of the new wefts and since this was my final tea towel I thought I’d take a chance and I switched my weft to a lime green. The lime had a bit of a blue tinge to it so I though it might work. I’m pleased with this one, it looks fresh and clean and now I wish I’d been brave sooner!

Needless to say I’m not in love with these tea towels and so I thought I’d forego my usual hand sewing on the hems and bring out the sewing machine. I’ve never done this before, but I just couldn’t see putting much more time into these tea towels that are now destined to be mailed to my son as they are the perfect colour to brighten up his apartment. I was really careful in my ironing before sewing and pinned the hems in place every 2 inches or so, but find that my stripes are not perfectly aligned, it seems to have gotten progressively worse as I sewed along the hem. Any suggestions on how to avoid this without purchasing a walking foot for my machine? Do I need to pin more frequently? I realize that it is the different speed between my feed dogs and the top layer of fabric, but if you have a fool proof method, please share!I also noticed after the fact that I’d hemmed one of the tea towels wrong side up and it’s really noticeable. Seems that this warp is one blunder after another!Here they are all together. From left to right is the lemon yellow weft, lime green weft, lemon yellow weft, dark yellow weft, lemon yellow weft and finally the butter yellow weft.

Here’s the draft:
