It all started when I found a fabulous Steve Madden satchel purse at Marshall’s. I am a deranged purse addict and it usually takes me weeks before I commit to one. This one had me at hello!

This beauty got my heart racing pretty fast, so I impulsively bought it and couldn’t have been happier….until I got home I saw the dreaded saggy slouch.

I always check purses out pretty well before I buy them. I like flat bottom purses with little metal feet and pretty fabric insides. This one passed all of the tests! when it was stuffed with paper.

Imagine my aggravation when I added my 40 lb wallet and makeup case to it and it wilted like a sad beautiful flower.

That’s when I had the idea for the quick purse fix! I have done this trick before with other handbags using cardboard but, after a while, the paper bends and reverts back to the slouch.

This time I improvised and used a stiff plastic lid from a divided beading/craft box and it came out fabulous!

DIY Purse Fix with Plastic Insert


  • Plastic Lid (mine is from a craft box), heavy cardboard/chipboard, or any type of material that will hold it’s shaping through wear and tear but is easy enough to cut through.
  • Sharp Scissors (I used the strong kitchen type) or Box Cutter,
  • Ruler
  • Washable Marker
measure a plastic craft lid to cut


make straight lines with a measuring tape
  • Take the plastic lid and measure the bottom of your handbag. Mark your lines with the magic marker.
cut the plastic with heavy duty scissors
  • Cut out your shape with sharp scissors. Trim slowly so you do not crack the plastic. Trim the edges and round the corners off.
plastic mold
  • Wash off the magic marker so you don’t ruin the inside fabric and insert it into the bottom of the handbag. You are done!

You could also go one step further and decoupage the plastic with fabric. I personally like the fact that it is clear so I can see if items get trapped underneath but to each his own.

  1. I might have to try this. It’s the sides and not the bottoms of my bag that are creasing. What containers do you use?

  2. Kim!!! This is great- I love your style of writing and vivid adjectives. My purse slouching is unfortunately not solved by this method. The bottom of my purse is fine but the slides are creasing because I don’t zip my purse up- and the low zippered sides pull downwards on both sides, resulting in an awful crease. But the inconvenience of constantly zipping and unzipping are just not practical. Do you have any ideas?

    1. Hi Mathia,
      Maybe try adding plastic to the sides as well. The container lids I used were simple bead boxes from Walmart.

  3. alane hill says:

    love the idea. But what can you do to fix the sides that have sloched down also. THe sides are as saggy problem.

    1. Hi Alane,
      It depends on the purse really. In this particular purse sides are fine when the base was added.

    2. I agree, I need some ideas for the sides that are slouching too!

      1. Maybe cut two more thin pieces of plastic for the sides and tape them to the bottom piece. I usually have so much stuff in mine that the side don’t slouch, lol.

    3. Hi
      I had a similar problem with sides, front and back of my bag slouching.
      I came up with an idea.
      I sent it to show/bag repair and asked them to put cardboard under the lining of the bag on all sides and bottom.
      It cost me £20 but I don’t mind it as it’s a designer bag.
      It came out really nice ?

        1. Hi Phyllis the sides of the bag are not reinforced. The plastic insert on the bottom straightens out the sides.

  4. Debs Dahm says:

    Ohhh i am so looking into fixing my nice but slouchy bag too using this tips. Currently, i put two small containers that fits perfectly at both corners. LOL.

  5. omg this is such a great idea!!! Like, totally genius! I am going to put this into effect asap!

  6. THIS. IS. ABSOLUTELY. AWESOME. I can’t even begin to tell you how awesome this is!!! I also have a 40 pound wallet (or so)… in fact, when I put my purse on my passenger seat with my wallet in it, my car beeps at me to tell me that my passenger isn’t wearing a seat belt! Yep… but this isn’t the worst of the problem, because, you know, I can always put my heavy purse on the floor. But what I HATE is buying a nicely structured purse and then walking around with it looking like a sloppy hobo bag because the items inside make it all slouchy. I am TOTALLY doing this trick!!! I’m off to pin this….

    Great idea! Thanks so much for sharing this on The Creative HomeAcre Hop! Hope to see you tomorrow on the next Creative HomeAcre hop!

  10. This is a great idea. What I hate most about the slouch is that everything is on top of each other in my purse when I reach in to get something. This would solve that too. May I feature this on my blog

  11. I’m thinking you are brilliant!!!! Love, love, love this idea!!!!!

    Thanks so much for partying at The DIY Dreamer.. From Dream To Reality! Can’t wait to see what you link up tomorrow evening!!

  14. Oh you smart savvy woman. Such a great idea for a problem that most of us have dealt with at one time or another. Liked your concept so much I had to feature it this week on BeColorful. Thanks for sharing.

  15. I hate the slouch too. Right now, I have a really thin book in the bottom of mine to prevent it from sagging. I’ll have to try out your trick.

  16. gardenoflisa says:

    Great idea! Found you on Thursday Favorite Things.

  17. You are featured this week on Busy Monday at A Pinch of Joy! I hope you will stop by and grab a Featured Button from the Button Box on the sidebar this afternoon. Pinned. Can’t wait to see what else you’ve been working on!

    What a great idea! I have the same problem with my purses! Thanks for sharing. Oh and by the way Total SCORE on that gorge purse! Visiting from Lil Luna’s Linky Party!

  20. Oh this is just terrific! I just bought a purse this week and literally the same thing happened and I was so disappointed (not enough to return it though). I’m off to find a plastic box lid :-) Oh and I found you through Fluster Buster.


  21. You are a genius, this is a fabulous idea. Thanks so much for sharing it.

  22. I have several slouchy purses/totes I’ll have to try this idea on — thanks for posting!

  23. You are so right about this – when I make bags I always use stiff stabilizer for the bottom or they all look too saggy. Thanks for linking to the Craftastic Monday party at Sew Can Do!

  24. It’s great how you thought of that! There are so many simple fixes out there, we just have to use our minds to brainstorm!

  25. So simple yet brilliant. I can’t stand when purses slouch. :) Thanks for sharing.

  26. Hi, visiting via Creative Mondays. This is such a simple, but clever solution to saggy purses. Unlike you, I buy purses like snap, :) Now I can hesitate even less, because of this nifty way of making them look better.
