So, I measured my dog around the middle...15 inches. He's a chubby toy poodle. I measured my old underwear down the center, and cut off the sides, leaving material around the crotch. I made it 18 inches in length, so I'd have room to overlap it at the back when it was done.
I ironed the fabric as best as I could, and folded the sides in by about a quarter inch, and then another quarter inch so that the cut edge wasn't showing.
Next, I folded the lengthwise sides together so that they overlapped in the middle.
Then I folded the short ends over twice, so that the raw edge doesn't show.
I sewed the short ends in place. (excuse the mess on my table; I was working on a doll earlier and left everything out).
After this step, I sewed across the short edge near the crotch area, making sure not to sew the actual crotch area. I wanted a pocket. I have a computerized Brother CS4000 machine, and the LCD light went out so I can't tell what stitch I'm choosing. I thought I was still doing a straight stitch, but I must have hit the stitch selection button because I got a surprise, lol.
Finally, I cut two pieces of that sticky mesh stuff...not velcro, but similar. I placed it on the ends and pushed so that it stuck. I pulled to see if I had to sew it on, but it had grabbed the fabric perfectly, so there was no need. I accidently snipped the fabric open when I cut this sticky stuff, and had to mend the weenie wrap; sigh.
I placed a pad in the pocket made at the crotch area.
And here is Ben checking his new weenie wrap out.
It's a perfect fit, and he seems content with it.
I'm happy with the way this turned out, and really happy that I can sleep without worrying that I'll wake up to another mess.
The next time, I'm going to use men's underwear, in a nice navy blue colour. Now that I know that old undies make great weenie wraps, I'll know to take more time with the cutting and measuring. I'm just a beginner, and I'm sure an experienced seamstress could make a really cute weenie wrap using this idea. It would be cute with some detailing on the outside; a ribbon around the edges, or a decal sewn on to the back.
If you try my pattern, let me know how it works for you.
If you have a bigger dog it would still work...you'd just need to add more fabric to make it longer on each end (or buy bigger undies ;-0).
