Dyeing - easiest fabric to use is 100% cotton, doesn't need lots of technical equipment - you can use ziplock bags and a packet or 2 of Dylon & salt. A large tray/roasting tin to stack the bags in is sensible. Chuck it & duck technique works great, if you want a more even finish keep agitating the fabric in the dye solution for 15-30 minutes (you don't need to put your hands in the dye, just massage the fabric through the plastic bag) Or you could get technical and do fancy pleating/stitching/tying or clamping before you toss the fabric in the dye bath(bag). The hardest part is the waiting - ie leaving it to soak in a few hours, and then leaving it in the rinse water for a couple of days (recommended for the avoidance of bleeding!), before drying & ironing - always a wonderful part.
As Maureen says it can be tricky to bring yourself to cut into them sometimes because they are unique each and every one
Here is an idea - how about we all dye up some fabric, and then send it to someone else to cut into and make up and then get it sent back to the original dyer? or is that just getting too ambitious?
