Memory Quilt
 

I plan to make a memory quilt for my great niece from her late mother's clothes, using the disappearing hourglass pattern. Several of her clothes were knit. I've ironed the back with the lightweight pellon. My question is do I also have to use the lightweight pellon on the back of the blocks? Thanks in advance. I've been a little hesitant to start with all the HST's.

Thank you.

You can if you want to but it is not necessary.

I have never done any quilting with knits except for t-shirts. They just get to bulky and stretchy for me to use. Good Luck.

As long as you've got the interfacing on the knit shirts, you do not need to put interfacing on the entire block.
