Used jeans
 

I have a rental unit and my tenants vacated, leaving a bag or two of old clothes. I checked the bag and there were a lot of old jeans in it, which I took. I want to make pet beds with them, the jean material on one side and outdoor fabric on the other for durability. I plan to stuff them with leftover pieces of fabric that I have for softness and birth the two, then stuff. What needle should I use to sew the pieces together? Should I wash the outdoor fabric first? I did wash the jeans. Can I make mug rugs with the jeans? I do not want to make a quilt, too heavy, but any other ideas?

I use a jeans or 16/100 needle when sewing heavy denim.

You can use needles that are called Jean Needles. They are probably size 16 or bigger. They really go thru the seams quite easily. I am always having to repair or hem my grandkids jeans so the are a must here.

As for the question of washing outdoor fabric, I would think it is already preshrunk since it has to hold up to the weather. Would not hurt to was if you are worried about it.

They make needles for jeans and canvas that are sturdy. My rule of thumb is to either wash all of the fabric that I'm using or none. Which considering the jeans were left behind I'd have washed them too. If they are going to shrink I'd want them to all shrink at the same rate; hopefully. Jeans also makes good rag quilts

Jean are great for making bags and purses. A google search will turn up a million ideas.

You can make a lot out of the pockets back pockets. Mini pocketbooks or cell phone. A hanging shelf - 3 - 4 or more
Make a back out of jean leg in a rectangle attach the b pockets on sides and bottom trim or not. Great for mail,
sewing items - make up - hang on wall, locker or car with a loop attached.

I made aprons using the back side & added cotton cloth ruffles on bottom of it and belt round waist

I too have made aprons that way. Red Bandana prints turn out really cute.

Don't discount the jeans for quilts. The younger set loves them. They are great for the beach, picnics, and in the car. I have made a lot of them. I don't quilt them, just tie with crochet thread. They are fabulous.
