Crochet and iron on backing

[Tlcjs93]

I have made some little blankets crocheted and I am going to be putting fleece on the other side and I struggle to sewing wool on my sewing machine and I wanted to know could I use iron on backing to make the blanket a bit firmer and easier to see the fleece 

I have added an image of what I'm working with 

 

Or of any one had any suggestion on easy ways to do this

Thanks xx

Hand sew.  That is the only solution that is going to work well and look well.

Iron-on anything only works on fabrics that can take high heat (cotton, wool) AND are finely woven (or finely machine-knit, like ironing on graphics on cotton T-Shirts.  Crochet fabric and fleece are much too coarse to stick together with iron on stuff.  Most fleece yardage, and probably your yarn are made of man-made plastic material that can't withstand the required heat.  Take it from someone who has been sewing her own clothes for decades, using iron-on interfacing and such, and knows what works and what doesn't, and ruined things finding out.

Cut out the fleece backing and sew it with the same yarn using a large eyed needle and a blanket stitch.  If you want, you could use the blanket stitch as a 'foundation  row' to add a simple crochet edging for a finishing touch.
