I've been working on my first sweater that involves steeks. I really wanted to machine reinforce them, but ended up not being able to figure out how to use a sewing machine and so hand sewed them up.
Now, the problem is that my hand sewing skills are better than those of a drunk hippopotamus with a lobotomy, but not much better. I'm really worried about my reinforcements coming loose, and in fact I've already noticed one stitch where that is happening.
Everything I've read says that you should wait until the entire garment is finished, even blocked, before sewing down the steek flaps. I can see that being preferable if there is no danger of them coming undone, but I'm going to be uneasy until I have them secured. Is it really that bad to pick up the stitches, knit an inch or so, and then whipstitch the steek flaps down before doing the rest of the sleeve?
