I often have people ask what kind of scissors I use for the rag quilts so here is my 2 cents
A pair of scissors with a short blade is a must. You can try to cut the blanket with your regular sewing scissors but you will not be able to cut all the layers at once and you will have more holes in your blanket from cutting the seams. The seams are not to hard to fix, but who wants to resew what they already sewed once.
Your hands will be sore, but you can do it. If you are only going to make one rag quilt in your entire life, don't go spend extra money on nice rag quilt scissors because it will be a waste of money.
I have 3 examples of scissors that I know work better than regular scissors for rag quilts. (click on the pictures for a link to where I found them. I have never purchased the scissors from the following stores, nor are they the best price. It is just where I found the examples)
I started out with a pair of scissors similar to this:
They worked great. Especially when I was just doing a blanket every once in awhile. Then when I started to sell the blankets I realized that those scissors would not cut it. I would have blisters and dents in my fingers from the handles. These scissors were about $10.00. They are called Dritz Fons Rag Scissors. The pair of scissors I started with were similar but not this exact brand.
This pair of scissors my sister in law uses and she loves them. She does several rag quilts each year. They are made by fiskars and are spring loaded so that your hand does not get as fatigued. The nice thing about these scissors is you still have a place for your fingers to go so the scissors do no slide along the handle very much. I cannot vouch for how many layers they will go through.
These scissors run about $15.00 but can be found at Joanns and other fabric stores. So make sure if they are not on sale to print off a coupon so you can get the best price possible.
These next scissors are the scissors that I use regularly. I am very biased because I am in love with them.
They are made by Heritage. These babies will cut through 7-8 layers of fabric at a time. They never make my hand fatigued. I am in love with them. They work like a charm. I do have one thing that I don't like about them (isn't there always something :) My hand slides up and down the handle as I am cutting. It does not hinder my cutting, just annoying.
If you have any questions about these scissors or any others please let me know. I would also love to know if you have favorite pair of scissors and what they are used for (even if you don't have rag quilt scissors)
