Just a couple of tips when buying rulers make sure they are the same brand as the measurements are not always the same. If you can afford a walking foot for straight sewing it will make it easier when sewing all the layers ie batting, front of work and back together as it helps feed it through more evenly. These are all things that i have found out the hard way...
Dont start with a huge quilt first up, make potholders and wall hangings that way you can practice all the techniques first without spending a lot of money on fabric and then when you feel more confident you can go out and splash out on all the beautiful fabrics there are out there! Also be careful with the rotary cutter as it is extremely sharp..use it as carefully as you would a razor blade and keep your fingers out of the way..always close it when not in use as a lot of people drop it and cut their toes. I think all the ladies have covered just about everything else and remember enjoy your quilting and dont get upset if it takes a while to get it right just go onto something else and then go back to it later. What works for one doesnt always work for another so try different things. Looking forward to see what you create!
