The handles are on the target so we’ve got something to hold on to but it still needs the
straps that you can put your arm through. On the one that I have, they are more like two
flaps sticking out but they velcro together. One side is sewn in and the other side is
connected using a metal ring through a loop that is sewn into the target. So that’s what
I’m going to try to replicate.
Here’s what I’m working from for this.
First I wanted to get the loop on the target created so I extruded the face from the target
a couple of times so that I would have a box sort of situation that I could remove the
faces to make a hole or tunnel through the item. Then I used connect to create the inside
faces. I really need to find a better way to do this. Getting to the edge I wanted in such
a tight space was not easy. I did try going to wireframe view but it was very difficult to
differentiate the edge I wanted from everything else. Several undos were needed for this.
Once I got the loops on the target created I selected the faces I could get to on one of
them and then copied them so that I had the loop that was going to be part of the strap. It
meant that I needed to close up the opening in bottom of that loop. So I created the face
to close that up and I had my other loop. At this point I decided to create the ring. Since
it’s a pretty rectantular looking ring I opted to use a box and edge loops to create it. I
will be applying the turbosmooth modifier to it later so that should round it out just
enough.
Even so, using a box to create the ring to connect the two loops wasn’t as straight on as I
thought it should be. Probably just me. But it took a bit of moving and adjusting to get
the size and shape just right. It also took some adjusting of the openings of the loops. I 
could get the ring nicely shaped but then it didn’t quite fit the opening right. Once I got the second loop and the ring created, I copied them to the other side. That cut down on some of the tweaking that was needed. Now, I just had to adjust the loop on the target.
You may notice in the image that the loops look a little strange. There is a reason for it but I didn’t catch it at this point. I just kept on modeling.
Since the strap that is sewn into the target is on the bottom I set to modeling that. First I extruded the top face of one of the places where the straps sewn to the back overlap. This gave me enough geometry to work with to create the strap. I extruded both of the side faces once and then just the top side face again 
to make a the longer part. Not bad. So I did the other one. Just two more straps to go.
From here it was time to create the straps on the other end. I used the top face and extruded it up, away from the surface so that I would have two layers. Then I extruded the side faces once and then deselected the bottom of the side faces and extruded just the top side face again only much longer. The same basic steps as before. I did that for the last strap as well. Next they needed to look like they are touching or velcro-ed together. This required angling the top strap down and the bottom one up a little. Selecting the edges was a little of a challenge at this point but with wire frame view turned on it helped.
I thought I was all set. I tried a render thinking this was going to be great. It wasn’t,
something was weird. The strap didn’t look right. The problem was one I haven’t dealt with much since I worked on the window frame on the dishes project. I had managed to get my normals flipped so it looked like they weren’t there you were just looking through them. At this point, it didn’t matter how I got them flipped, I just needed to see which ones they were and fix them. SO I turned on the option to view the normals direction and then I
right-clicked on the faces that needed to be flipped and chose the flip normal option. All
fixed. And now it looks like this.
As you can see from the picture at the top, these targets are not this sharp and square. I will need to refine them and make them look like they are filled with foam and have been beaten on. But, for now, the basics are there.
