Hello! I'm new to this forum, hello to you all! I have a question for those of you that use u-haul padded fleece liners or have made them yourself 
I am a new owner of two adorable 6-month old girls. I recently upgraded their cage to a 3x5 C&C so they have tons of room to run around!
I purchased some fleece material and padding and am going to be paying a seamstress friend to sew some liners for me. I just want to confirm the best way to go about making them so that they hold up for many years! I have heard that sometimes the U-Haul furniture pad shrinks as it is 100% cotton, while the fleece does not. I've read that making the liners a few inches larger help with preventing everything bunching up over time.
I also read that one lady who makes her own liners sews the fleece together and then leaves a pocket open to place the padding inside so it's easier to replace in the future if needed. Does anyone have any experience with this or think this is a better option than sewing it all together? The fabric was quite expensive so I would like to do whatever I can to prevent shrinkage and ruining the liners down the line.
Really appreciate any input, and apologies if this has been asked before. Thanks!
