Two clothing repair challenges

It turns out my clever plan to reinforce the thighs of my corduroy pants with a honeycomb stitch really wasn't all that clever. It took me at least two hours to stitch both sides of the pants, and within three months, they were falling apart again. Not only had the threadbare area expanded well beyond the borders of the original darn, but the threads in the darned area itself had worn through and broken off in several places. This left nothing to protect the fabric underneath, which had started to develop actual holes. They were still small, but clearly re-darning the area wasn't going to do much to keep them from growing. If I wanted to save the pants, I was going to need a new fix.

Since darning hadn't worked, I decided to move on to an entirely different technique: patching. I didn't have any fabric remotely similar to the original grey corduroy, so I decided to go for a complete contrast instead. Down in my scrap bin, I had a fairly good-sized bolt of colorful striped fabric in good condition that we'd picked up at a yard sale or somewhere. I cut two pieces of this large enough to cover the threadbare areas on both thighs, right over top of the honeycomb stitching. That saved me the bother of picking it all out (and possibly weakening the fabric in the process). 

I left a little extra space around the edges of each patch so that I could hem them. I folded over the raw edge and sewed it down using a back stitch. They came out a little bit lumpy, but more structurally sound than just a chopped-off piece of fabric. 

Then, using my usual whip-stitch technique, I sewed the two patches in place. My first attempt was a little messy, as I didn't pin the fabric down first; I just followed the line of the seam in the pants. That worked fine along that one edge, but it didn't secure the entire patch well enough to keep it smooth and flat, so the fabric underneath ended up a little puckered. I couldn't bring myself to pick out the seams and do it over, but I did make a point of carefully pinning the second patch before stitching it so that it would come out neater.

All told, this repair took me a couple of hours, about the same as the first one. But I'm hoping it will hold up longer and maybe justify the amount of effort I put into it.

Sadly, I don't think there's any equally simple fix for the wardrobe item that most recently fell apart on me: my two-year-old black ankle boots. They already had cracks in the sole that Shoe Goo had proved unable to fix, making them too leaky to wear in the rain. But when I wore them out on a walk today, one corner of the heel simply disintegrated, leading me to suspect that I won't be able to wear them even in dry weather for much longer. 

You can't replace the heels on a cheap pair of boots like this, and at this point, there's so little left of the sole that there wouldn't really be anything to attach it to anyhow. The only question is whether I can come up with some sort of hack that will allow me to get another couple of months of use out of the boots—long enough to get me through the multiple rounds of trial and error it will no doubt take me to find a replacement.
