Serging Blanket Edges

A quick blanket using fleece is a quick gift idea for friends, or if you are always travelling to sports events with the kids, blankets come in handy at those evening soccer games, cooler football games, and of course hockey to only name a few.......In photo below decorative thread has been used on the serger, and this can be achieved by using 3 thread wide, 2-thread overlock wide, or 2-thread wrapped overlock wide application. Any of these three will work for blankets.

This blanket is actually double thickness with contrasting solid on reverse side.

Fleece, cotton flannel, wool, are all great possibilities for blankets.

Corners can sometimes ripple when you least expect it , if fabrics are very stretchy. Practice on a small piece of the same fabric you are using for your blanket. Adjust your differential feed accordingly. (see your manual if you are not sure). 
If your fabric is very very stretchy, using a piece of water soluble stabilizer, just underneath the corner will prevent any further rippling. 
Very occasionally bias cut projects require adjustments in differential feed and use of stabilizers depending on the type of project. 

Embroidery can be done directly on the blanket or they can be created as appliques as seen above.

 If you are in a pinch and need a very fast gift, purchase a ready made blanket as this white one above. If your sewing machine has machine embroidery capabilities, machine embroidery on a separate piece of fabric, the word friends, or the name of the friend, or even their favourite theme. Embroider a number of them in one sitting leaving enough space around each one to cut them each out. Using your serger and a narrow or rolled hem, stitch around the 4 edges. This is very good practice for serging corners. This blanket shown has approximately 10 of the Friend appliques. Stitch them on with your sewing machine. Use a straight stitch or a pretty decorative stitch. 
Have fun.
