I made this bag last night (the pictures show each side of the bag - the pictures are of my gorgeous boys!!!) using a homemade bubble jet set recipe I have been experimenting with. I was so excited that it worked, I want to share it with all you gorgeous craftsters:

I also made this cosmetic bag using the same process:
****Now been edited to change the recipe - the new one is better!!****Here's how I did it.
Firstly choose your fabric. It needs to be 100% cotton or 100% silk (haven't tried it with silk). Cut it to a little larger than the paper you run through your inkjet printer.

Then get your equipment. Yup - just like cooking!!!

Here's the recipe (the percentages are by weight - NOT volume):
85% hot water
10% washing soda (the crystal type - it's also known as Soda Ash)
5% fabric softenerHere's the new recipe (the percentages are by weight - NOT volume):85% hot water
10% alum
4% washing soda (also known as Soda Ash)
1% fabric softener
So, as an example, if you wanted to make 300g, you would mix:
255g hot water
30g alum
12g washing soda
3g fabric softener
When you mix all the ingredients, it will foam up - don't worry the foaminess will subside and you will be left with a liquid. (It will look different to the picture below)
In this next photo you will see I have added the ingredients (but not stirred them):

Next add your fabric to the mixture. Let it soak for 5-10 minutes. Hang the fabric to dry. If you are in a hurry, you can blast the fabric with the hairdryer to dry.

While you're waiting for the fabric to dry, save any leftover and store in a labelled jar:

Once your fabric is dry, you need to adhere the fabric to something to allow it to go through the printer. I have had success with ironing it to iron-on interfacing. In this example, I glued the fabric to the paper using spray glue (I also used a piece of sticky tape on the first edge to go through the printer so that the fabric wouldn't lift off the page when the printer intially "grabs" the fabric/paper and jam the printer.) You could also use freezer paper.
Then you trim the fabric to fit the paper:

Then print your image onto the fabric/paper. I just used Microsoft Word to strategically place the photos on the fabric. When printing use the highest quality setting.

Once your image is on the fabric, wait 20 minutes*(see
EDIT below) before rinsing the excess ink from the fabric. Remove your paper backing. Put some cold water and a little fabric softener in a sink, dunk the fabric straight in and give it a quick swish. At this point, you will lose some of the colour. I guess you need to start with a dark/high contrast photo (I haven't experimented greatly). The fabric softener is a mild detergent.

Wring out excess water then leave to dry. The next photo shows when I have just wrung out the fabric and is still wet:

Once dry, you are now ready to make something with your creation!!!
EDIT: If you are using genuine ink cartridges, you can leave the print for 20 minutes before rinsing but if you are using generic ink cartridges, leave the print overnight before rinsing. There should be no fading.
When washing, only use a
mild detergent such as fabric softener or
handmade soap.
And one more tip - only treat as much fabric as you will use in a day (this is a tip from Bubble Jet Set instructions).
Post here if you have any other tips/suggestions - I would love to see what other craftsters come up with.
ENJOY !!!
