It looks to me like the legs on the squirrel you refer to are made in two parts. The feet themselves are one part, and made like a closed tube, and the leg looks like it is made in a flattish sort of circle. Have you thought about writing to darncat and asking her if she'd be willing to share the idea of her 'floppy feet'? If not, maybe I could help you design what you're looking for.
Assuming that thes handles have the little rings on the bottoms to attach to the bag, I like to crochet little tabs to attach this type of handles to my bags. I think it gives it a more finished, professional look.
I am not the best at lining purses and bags, but I find myself doing it more and more often now, so maybe I can offer some help here, if only by telling you how I do it. My methods are kind of down and dirty, nothing fancy.
I have two ways of making a lining for a purse. If the purse is fairly "flat", i.e. not much of a bottom, I flatten the bag out, then lay it on the fabric I want to line it with. then trace around it leaving a good half inch border all the way around between the purse and the line I am tracing for a hem. Please make sure you have doubled the fabric before you do this, so that when you go to cut it out, you will have two pieces. Also, I recommend using a pair of pinking shears to cut the fabric, so that it is less likely to fray. I don't have a sewing machine, so I hand sew the seams starting at one top corner, down, across the bottom, and back up the other side. Then I fit the purse lining into the purse itself, and turn the top edges down, pinning them into place around the top of the bag. I whipstitch the lining into the bag, usually a half to a quarter of an inch down from the top edge of the bag. This is the fairly easy method.
For a bag with a more defined bottom, either a definite oval, square or circle, I make sure I trace that bottom on to a piece of paper before I begin to crochet up the sides. That way I have a template to use for the purse lining. Then when the bag is finished, again, I flatten it out, and leaving at LEAST an inch between the bag and tracing line, I trace the bags sides and tops. I also trace around the bottom template that I traced onto a piece of paper earlier, again leaving at least a good inch between the template and the fabric. After cutting out the fabric, I pin the two sides to the bottom, then pin the sides together, and sew. Sometimes you need to fiddle the two sides to the bottom, it's not an exact science, at least not for me. Then I fit the lining into the purse, and proceed as I do the easy method, turning down the hem, pinning into place and whipstiching the fabric into the purse.
As for handles or straps that won't stretch dramatically out of shape, I use a number of methods.
Method One: The easiest is to do a alternative reverse single crochet stitch all around the top and both sides of the straps. This is done by inserting the hook into the stitch as you normally would start a single crochet, yarn over, draw through so that you have two loops on your hook, then turn your hook 360 degrees (yes, you are twisting those two loops of yarn!) yarn over, and draw through the two loops. This forms a surprisingly sturdy edge to the top of your purse and the straps.
Method two is to do your straps separately from your purse, chaining the length you want, and doing two rows of double crochet, then sew an appropriate length of binding tape to the top and bottom of one side of the double crochet. Fold the other side over the binding tape and single crochet through both thicknesses. Sew the straps in place on your purse. I use this method frequently in making straps for backpacks.
Method three is to make tubes of fabric and sew them to the underside of your straps.
Forgive me if I've been overly wordy here. I hope this is of some help.
I've got major Spring Fever, and while waiting for signs of flowers to pop up around here, I was inspired to make this flower tote. I think the rows of flowers and leaves look like tulips, or at least I hope they look like it, but my daughter says they are roses, daffodils, and tulips. Works for me!
It's a pretty big tote, for me at least, as you can see from the 12 inch ruler propped on the front here:
I made the bag using Bernat Softee Chunky yarn in Natural, Medium Sea Green, Too Purple, True Yellow, and Carnival. Here's a close-up of the popcorn stitches I used to form the flowers and leaves.
I've also done a back pack version of the same design, only with all purple flowers, and purple trim. I have to finish the straps for that one though. I'd love to know what you think.
